Risk Factors Related to Gestational Trophoblastic Disease

Background: Gestational trophoblastic diseases (GTD) consist of a group of neoplastic disorders arising from placental trophoblastic tissue after normal or abnormal fertilization. The WHO classification of GTD includes hydatidiform mole, invasive mole, choriocarcinoma, placental site trophoblastic tumor, and miscellaneous and unclassified trophoblastic lesions. This study aimed to analyze the risk factors related to the gestational trophoblastic disease. Material & Methods: This prospective study was conducted at the Department of Obstetrics & Gynecology in Uttara Adhunik Medical College & Hospital, Dhaka, Bangladesh for 1 year; from April 2020 to March 2021. A total of 100 subjects were included in this study. Informed written consent was taken from the study subjects. Data was collected using a pre-formed data sheet. Data processing and analysis were done by using SPSS version 17. The test statistics used to analyze the data were descriptive statistics, the McNemar Chi-square test, and Repeated Measure ANOVA statistics. All patients underwent necessary investigations. All information was kept confidential and used only for this study purpose. The ethical Clearance Certificate was obtained from Bangladesh Medical College. Results: The majority of the patients were more than of 38 years age (53, 53.0%). Out of these patients, 50 (50.0%) were para one, while 40 (40.0%) were para more than four, most of the patients (63, 63.9%) were illiterate and 5 (5.0%) were graduates, most of the subjects (73, 73.0%) belonged to the low socioeconomic group. The most common presenting symptom was bleeding per vagina (35, 35.0%) followed by pain in the lower abdomen (24, 24.0%), the passage of moles (16, 16.0%), hyperemesis gravidarum (14, 14.0%) and dyspnea in 11 (11.0%) subjects. Conclusion: The disease was common in extremes of ages, low para, and grand multiparous women. The hydatidiform mole was the commonest type of trophoblastic disease in these patients. The most common presenting complaint was bleeding per vagina followed by pain in the lower abdomen. The hydatidiform mole was diagnosed in 65 (65.0%) patients, the invasive mole in 28 subjects (28.0%), and choriocarcinoma in 7 (7.0%) patients. No patient had a placental site trophoblastic tumor.

Diagnóstico y tratamiento quirúrgico de una paciente con una neoplasia trofoblástica gestacional / Diagnosis and surgical treatment of a patient with gestational trophoblastic neoplasia

Resumen ANTECEDENTE: La neoplasia trofoblástica gestacional forma parte del grupo de afecciones derivadas de la proliferación anómala del trofoblasto con capacidad para invasión y metástasis. CASO CLÍNICO: Paciente de 42 años, asintomática, con sospecha ecográfica de mola hidatiforme. El legrado uterino y el estudio anatomopatológico confirmaron el diagnóstico de mola hidatiforme completa. Con la cuantificación consecutiva de tres elevaciones de la β-HCG se diagnosticó: neoplasia trofoblástica gestacional. Se estadificó en estadio I, bajo riesgo y ante el deseo genésico satisfecho la paciente aceptó la histerectomía más salpingectomía bilateral. En el seguimiento posterior la paciente se encontró asintomática, con determinaciones seriadas de b-HCG negativa y ecografías vaginales sin hallazgos. CONCLUSIÓN: La histerectomía con salpingectomía bilateral puede ser el tratamiento definitivo en casos seleccionados de neoplasia trofoblástica. La evidencia disponible es escasa, por lo que es necesario seguir investigando en este campo.

Abstract BACKGROUND: Gestational trophoblastic neoplasia is one of a group of conditions resulting from abnormal trophoblast proliferation with capacity for invasion and metastasis. CLINICAL CASE: 42-year-old asymptomatic patient with ultrasound suspicion of hydatidiform mole. Uterine curettage and anatomopathological study confirmed the diagnosis of complete hydatidiform mole. With the consecutive quantification of three elevations of β-HCG a diagnosis of gestational trophoblastic neoplasia was made. It was staged as stage I, low-risk, and the patient agreed to hysterectomy plus bilateral salpingectomy. At subsequent follow-up the patient was found to be asymptomatic, with negative serial determinations of β-HCG and vaginal ultrasound scans without findings. CONCLUSION: Hysterectomy with bilateral salpingectomy may be the definitive treatment in selected cases of trophoblastic neoplasia. The available evidence is scarce and further research is needed in this field.

Mola hidatiforme completa en mujer premenopáusica. Caso clínico / Complete hydatidiform mole in a perimenopausal woman. Clinical case

Resumen ANTECEDENTES: La mola hidatiforme se divide en completa y parcial. La primera se origina en la fecundación de un óvulo anucleado por dos espermatozoides con carga genética independiente y la manifestación clínica predominante son las hemorragias. El tamaño uterino suele ser mayor al normal, con síntomas subjetivos del embarazo. La importancia de este tipo de tumoración es su carácter premaligno que puede evolucionar hasta convertirse en una neoplasia trofoblástica, de tal manera que en la mola completa se transformará en neoplasia. CASO CLÍNICO: Paciente de 43 años que acudió a consulta debido a la caída de su plano de sustentación 3 días antes, con dolor pélvico en el hipogastrio, tipo cólico de intensidad moderada, sin sangrado transvaginal. Refirió estar embarazada, sin recordar la fecha de la última menstruación; sin control prenatal ni ultrasonido previo. A la exploración física el abdomen se encontró globoso, a expensas de útero hipertrófico de 16 x 12 x 10 cm, concentraciones de HGCß mayores de 150,000 mUI/mL. El ultrasonido endovaginal y pélvico reportaron: útero en anteversoflexión, central, aumentado de tamaño por imagen ecográfica en copos de nieve. Diagnóstico: mola hidatiforme. Se indicó la histerectomía abdominal, con hallazgos de útero aumentado de tamaño a expensas de mola completa y anexos sin alteraciones. CONCLUSIÓN: El diagnóstico de la paciente fue fortuito, advertido en el ultrasonido. La conducta terapéutica establecida para este tipo de casos en pacientes mayores con paridad satisfecha permitió que la evolución fuera satisfactoria y continuar en seguimiento.

Abstract BACKGROUND: Hydatidiform mole is divided into complete and partial. The former originates from fertilization of an anucleate ovum by two spermatozoa with independent genetic load and the predominant clinical manifestation is hemorrhage. The uterine size is usually larger than normal, with subjective symptoms of pregnancy. The importance of this type of tumor is its premalignant character that can evolve into a trophoblastic neoplasm, so that in the complete mole it will transform into a neoplasm. CLINICAL CASE: 43-year-old patient who came for consultation due to the fall of her support plane 3 days earlier, with pelvic pain in the hypogastrium, cramping of moderate intensity, without transvaginal bleeding. She reported being pregnant, without remembering the date of her last menstrual period; no prenatal check-up or previous ultrasound. On physical examination the abdomen was found to be globose, at the expense of a hypertrophic uterus measuring 16 x 12 x 10 cm, HGCß concentrations greater than 150,000 mIU/mL. Endovaginal and pelvic ultrasound reported: anteverted, central, enlarged uterus with snowflake-shaped ultrasound image. Diagnosis: hydatidiform mole. Abdominal hysterectomy was indicated, with findings of an enlarged uterus at the expense of complete mole and unaltered adnexa. CONCLUSION: The patient's diagnosis was fortuitous, noticed on ultrasound. The therapeutic approach established for this type of case in older patients with satisfactory parity allowed for a satisfactory evolution and continued follow-up.

Mola hidatiforme parcial con feto vivo sano a término / Partial hydatidiform mole with healthy live fetus reaching term

Resumen ANTECDENTES: El embarazo molar parcial, con feto vivo sano coexistente, es una forma rara de las molas hidatiformes. Debido a los pocos casos reportados se carece de guías que marquen la pauta para la atención médica de estas pacientes. Si bien el riesgo de complicaciones obstétricas en estos casos es alto, un gran porcentaje de las pacientes puede llegar a tener un recién nacido sano. CASO CLÍNICO: Paciente de 29 años, primigesta, con embarazo espontáneo. A las 23.3 semanas se detectó, por ultrasonido, que la placenta tenía múltiples imágenes anecoicas en su interior, un patrón en "racimo de uvas" que sugería un posible embarazo molar. La paciente decidió continuar con el embarazo a pesar de haberle explicado los riesgos obstétricos. Durante el resto del embarazo cursó con hipertensión gestacional y trombocitopenia, quizá gestacional. Se decidió la finalización del embarazo por vía abdominal a las 38 semanas. El reporte histopatológico corroboró el diagnóstico de mola hidatiforme parcial. CONCLUSIÓN: El momento de finalización del embarazo se determina con base en las complicaciones de la madre o el feto. Es importante la adecuada comunicación con la paciente.

Abstract BACKGROUND: Partial molar pregnancy with coexisting healthy living fetus is a rare form of hydatidiform molas. Due to the few reported cases, there is a lack of guidelines for the medical care of these patients. Although the risk of obstetric complications in these cases is high, a large percentage of patients may go on to have a healthy newborn. CLINICAL CASE: A 29-year-old primigravida patient with a spontaneous pregnancy. At 23.3 weeks, the placenta was detected by ultrasound to have multiple anechoic images in its interior, a "cluster of grapes" pattern suggesting a possible molar pregnancy. The patient decided to continue with the pregnancy after the obstetric risks were explained to her. During the remainder of the pregnancy she presented with gestational hypertension and thrombocytopenia, perhaps gestational. It was decided to terminate the pregnancy by abdominal approach at 38 weeks. The histopathological report corroborated the diagnosis of partial hydatidiform mole. CONCLUSION: The timing of termination of pregnancy is determined based on maternal or fetal complications. Adequate communication with the patient is important.

The possible association between the types of soft palate and gag reflex: a preliminary study / A possível associação entre os tipos de palato mole e o reflexo de vômito: um estudo preliminar

Objective: whether gag reflex, a common problem encountered during dental procedures, is associated with the different types of the soft palate has not been addressed so far. This preliminary study sought to assess the potential association between the different types of soft palate and gag reflex. Material and Methods: one hundred dental patients were recruited. The type of soft palate was determined. Subjective (self-reported) gag reflex was recorded based on many questions and past experience and on a 0-6 VAS. Objective assessment of gag reflex was done using different maneuvers where the posterior part of the tongue and the soft palate were touched by dental mirror, and by taking impression for the upper arch. The association between the types of soft palate and the subjective and objective recorded gag reflex were statistically tested. Results: there were 53 (53%), 33 (33%) and 14 (14%) of the participants with class I, class II and class III soft palate, respectively. A significant association was found between the type of the soft palate and gag reflex in response to one of the subjective items (P= 0.039), more prominent among females (P= 0.009). Concerning the objective assessment, no significant associations were found among males. Meanwhile more females with class II and class III suffered gag reflex and/or actual gagging upon taking the impression (P = 0.001). Conclusion: this study illustrated an association between the type of soft palate and gag reflex, and its severity in females (more specifically soft palate types II and III) more than in males (AU)

Objetivo: o reflexo de vômito, um problema comum encontrado durante procedimentos odontológicos, está ou não associado aos diferentes tipos de palato mole, não foi ainda abordado até o momento. Este estudo preliminar procurou avaliar a possível associação entre os diferentes tipos de palato mole e o reflexo de vômito. Material e Métodos:cem pacientes odontológicos foram recrutados. O tipo de palato mole foi determinado. O reflexo de vômito subjetivo (auto-relatado) foi registrado com base em muitas perguntas e experiências anteriores e em um VAS de 0-6. A avaliação objetiva do reflexo de vômito foi feita por meio de diferentes manobras onde a parte posterior da língua e o palato mole foram tocados por espelho dental e por meio de moldagem da arcada superior. A associação entre os tipos de palato mole e o reflexo de vômito subjetivo e objetivo registrado foi testada estatisticamente. Resultados: houve 53 (53%), 33 (33%) e 14 (14%) participantes com palato mole classe I, classe II e classe III, respectivamente. Foi encontrada associação significativa entre o tipo de palato mole e o reflexo de vômito em resposta a um dos itens subjetivos (P= 0,039), mais proeminente no sexo feminino (P= 0,009). Em relação à avaliação objetiva, não foram encontradas associações significativas entre os homens. Enquanto isso, mais mulheres com classe II e classe III sofreram reflexo de vômito e/ou engasgo real ao receber a impressão (P = 0,001). Conclusão: este estudo ilustrou uma associação entre o tipo de palato mole e reflexo de vômito e sua gravidade em mulheres (mais especificamente palato mole tipos II e III) mais do que em homens.

Ornithodoros mimon colonizing a residence in Campinas, state of São Paulo, associated with human parasitism / Ornithodoros mimon colonizando uma residência em Campinas, estado de São Paulo, associado a parasitismo humano

Ornithodoros mimon is an argasid tick species usually associated with bats and marsupials and occasionally parasitizes humans inside their homes. This paper reports a tick infestation in a residence in the municipality of Campinas, located in the interior of the state of São Paulo (SP). This report increases O. mimon occurrence in SP and corroborates its anthropophilic activity. Further studies are needed to clarify its role as a vector of pathogens. We highlighted the presence of O. mimon in an area with a large human population (Campinas) associated with synanthropic animals.(AU)

Ornithodoros mimon é uma espécie de carrapato argasídeo, geralmente associada a morcegos e marsupiais, sendo ocasionalmente relatada parasitando humanos dentro de seus domicílios. Este trabalho relata a infestação por carrapatos em uma residência no município de Campinas, interior do estado de São Paulo (SP). O presente relato amplia a ocorrência de O. mimon no estado de SP, corroborando sua atividade antropofílica, sendo necessários mais estudos para esclarecer o seu possível papel como vetor de patógenos. Destaca-se a presença de O. mimon numa área de grande contingente humano (Campinas), associado a animais sinantrópicos.(AU)

Initial management of hydatidiform mole

Introduction: Hydatidiform mole is a type of gestational trophoblastic disease that results from the abnormal fertilization of an oocyte and causes nonspecific symptoms such as amenorrhea, metrorrhagia, and enlarged uterus. Although rare, its most characteristic symptoms include hyperemesis, early-onset pre-eclampsia, anemia, and respiratory distress. Case presentation: A 47-year-old Moroccan woman consulted the emergency department of the Hospital Clínico Universitario in Valladolid (Spain) after a month of persistent coughing and emesis. The patient reported epigastralgia and amenorrhoea for two months, as well as scant vaginal bleeding two days prior to consultation. Taking into account that the patient tested positive for pregnancy, that a heterogeneous intrauterine mass measuring 124x120mm was observed on transvaginal ultrasound, that no abnormal findings were reported on Doppler ultrasound, and that her serum ßhCG levels reached a value of 772.110 mIU/mL, a diagnosis of hydatidiform mole was suspected. Once informed about the possible therapeutic options, the patient decided to undergo a total hysterectomy, as she stated that she had already fulfilled her desire to be a mother. After the procedure, the patient's clinical condition improved, and the pathology report of the mass confirmed the diagnosis of partial hydatidiform mole. Conclusion: Early diagnosis of hydatidiform mole is paramount in order to provide adequate treatment and improve the prognosis of these patients. Therefore, despite its low incidence and non-specific clinical manifestations, it should be considered as a differential diagnosis for first-trimester metrorrhagia.

Introducción. La mola hidatiforme es un tipo de enfermedad trofoblástica gestacional que se presenta como resultado de la fertilización anormal de un ovocito y que ocasiona síntomas inespecíficos como amenorrea, metrorragia y aumento del tamaño del útero. Aunque infrecuentes, sus síntomas más característicos incluyen hiperémesis, preeclampsia de inicio temprano, anemia y distrés respiratorio. Presentación del caso. Mujer marroquí de 47 años que consultó al servicio de urgencias del Hospital Clínico Universitario de Valladolid debido a que había presentado tos y vómitos por un mes. La paciente refirió haber sufrido epigastralgia y amenorrea por dos meses, así como escaso sangrado vaginal en los últimos dos días. Teniendo en cuenta que la paciente dio positivo en una prueba de embarazo, que en la ecografía transvaginal se observó una masa intrauterina heterogénea de 124x120mm, que no se reportaron hallazgos anormales en la ecografía Doppler y que sus niveles séricos de ßhCG alcanzaron un valor de 772.110 mUI/mL, se sospechó un diagnóstico de mola hidatiforme. Una vez informada sobre las posibles alternativas terapéuticas, la paciente decidió someterse a una histerectomía total, pues refirió que ya había cumplido su deseo de ser madre. Luego de realizar procedimiento, la condición clínica de la paciente mejoró; además, el informe de patología de la masa permitió confirmar el diagnóstico de mola hidatiforme parcial. Conclusiones. El diagnóstico temprano de la mola hidatiforme es de gran importancia para ofrecer un tratamiento adecuado y, de esta forma, mejorar el pronóstico de estas pacientes. Por tanto, a pesar de su baja incidencia y sus manifestaciones clínicas inespecíficas, se debe considerar como diagnóstico diferencial de las metrorragias del primer trimestre.

Histomorphological Analysis of Gestational Trophoblastic Disease Spectrum with Clinicopathological Correlation at a Teaching Hospital

Introduction: Clinically, all trophoblastic lesions are frequently combined under a broad spectrum of gestational trophoblastic diseases (GTDs)without the use of specific pathological terms. However, studies now demonstrate that various forms of GTDs demonstrate differences in etiology, histogenesis, morphology, and clinical behavior. Thus, the need for diagnostic histopathology of these lesions to distinguish gestational trophoblastic neoplasms from nonneoplastic lesions and molar pregnancies and also for early anticipation for early anticipation, risk category stratification, prognostication, management, and prediction of persistent GTD. Our study aimed to study the histomorphological patterns of various types of GTD with light microscopy and the pattern of occurrence of GTDs in relation to age, parity, and gestation. MaterialsandMethods: The present study was conducted in the department of pathology, from January 2020 to April 2022. All GTDs confirmed by histopathological examination by hematoxylin‑ and eosin‑stained slides were included. Results: The spectrum of GTDs found in this study was seventy cases of hydatidiform mole (92.10%), three cases of exaggerated placental site (EPS) reaction (3.94%), and two cases of choriocarcinoma (2.63%) and one case (1.31%) of placental site trophoblastic tumor (PSTT). The most common presenting symptom was vaginal bleeding (93.42%). Conclusion: Hydatidiform mole forms the most common type of GTD with an incidence of complete moles more than partial moles. Histomorphological examination and analysis are helpful for confirmatory diagnosis. The most common clinical presentation of GTD was vaginal bleeding followed by amenorrhea. Emphasis on detailed descriptive morphological assessment can help in the histological distinction of benign lesions such as EPS reaction and placental site nodule and avert such cases from being erroneously diagnosed as neoplastic. The Ki‑67 proliferation index helped in distinguishing the EPS reaction from neoplastic lesions such as PSTT which requires surgical intervention and chemotherapy.

Multiple Epidermoid Cysts of Face: A Case Report

Introduction: Epidermoid cysts are cystic malformations filled with keratin and lipid rich debris. They generally present as benign, soft, and freely movable, slowly enlarging, and non-tender masses, commonly located on the face, neck and trunk of the body. They are more commonly seen in ovaries and gonads, and less often in head and neck region. Approximately 7% of epidermoid cysts are present in the head and neck region and about 1.6% are found in the oral cavity. They can be either congenital or acquired in origin. Congenital epidermoid cyst occurs at third and fourth intra-uterine life due to entrapment of ectodermal elements entrapped during midline fusion of first and second branchial arches. However, acquired epidermal cysts occur due to implantation of epidermal elements following cystic transformation. Case presentation: In this article, we discuss a case of epidermoid cysts presenting in multiple areas of the face which clinically appeared to as acquired nevi (mole). Management/Prognosis: Based on clinical appearance and provisional diagnosis, treatment of mole was made. The lesions were excised by electrocautery and sent for histopathological evaluation. Conclusion: There was a drastic difference between the clinical appearance and histopathological picture seen. A thorough knowledge about etiology, clinical history and histopathology is needed to reach an accurate diagnosis

Sad fetus syndrome: A case report / Philippine Journal of Obstetrics and Gynecology

@#Sad fetus syndrome is a rare gestational trophoblastic disease wherein a hydatidiform mole coexists with a live fetus. We report a case of a 40‑year‑old G4P2 (2012) with 29 weeks gestational age who came in with vaginal bleeding and labor pains. A previous ultrasound done at 16 weeks of gestation showed a live fetus, a normal placenta, and a focal multicystic uterine mass. The beta‑human chorionic gonadotropin level was 1,500,000 mIU/mL. She delivered a live preterm female fetus weighing 900 g by partial breech extraction. The placenta was grossly normal. Postpartum hemorrhage secondary to uterine atony was encountered and a total hysterectomy with bilateral salpingectomy was performed. Cut section of the specimen revealed molar tissue at the anterofundal area with evidence of gross myometrial invasion. The histopathologic finding was consistent with a diagnosis of partial hydatidiform mole. This paper describes the incidence, pathology, clinical presentation, diagnosis, treatment, and postpartum course of this rare condition.

Persistent trophoblastic neoplasia in the broad ligament, a case report / The Health Sciences Journal

@#Gestational trophoblastic neoplasia (GTN), a malignancy arising from trophoblastic tissue of pregnancy, is an aggressive disease process with a high probability of metastasis if left untreated. This is a case report on metastatic invasive mole arising from a molar pregnancy. Four months after suction curettage, a mass was noted in the left broad ligament on exploratory laparotomy with intact uterine serosa. Clinical presentation, biochemical, and radiological parameters led to a diagnosis of persistent trophoblastic disease. Histopathological findings also confirmed the diagnosis. Prompt chemotherapy was given after removal of the left intraligamentary mass, and subsequent response to treatment was documented. We report a case demonstrating a different clinical presentation of invasive mole and its potential to metastasize to the broad ligament without uterine perforation or direct extension.

Tirotoxicosis por enfermedad trofoblástica gestacional: revisión a partir de 3 casos / Thyrotoxicosis due to gestational trophoblastic disease: clinical cases

La enfermedad trofoblástica gestacional (ETG) es una complicación del embarazo poco común. Corresponde a un espectro de lesiones proliferativas del tejido trofoblástico: Mola Hidatiforme (MH) en sus formas parcial y completa, Coriocarcinoma, Tumor Trofoblástico y Tumor Trofoblástico Epiteloide. Los distintos tipos de ETG presentan en común la hipersecreción de gonadotrofina coriónica humana (hCG). La hCG es una hormona glicoproteica con una estructura muy similar a la TSH, por lo cual puede estimular la función tiroidea en condiciones fisiológicas y en algunas condiciones patológicas. La ETG puede cursar con hipertiroidismo, el cual puede variar en intensidad, desde una presentación asintomática con alteración leve de hormonas tiroideas a un cuadro de hipertiroidismo manifiesto. Se presentan 3 casos clínicos de pacientes con ETG, específicamente MH que evolucionaron con tirotoxicosis transitoria. Los casos presentaron un cuadro leve de hipertiroidismo con pocos síntomas asociados. La taquicardia fue el único síntoma en la mayoría de los casos. En todas las pacientes las hormonas tiroideas se normalizaron después del tratamiento de la ETG. Conclusión: Se debe tener presente la posibilidad de hipertiroidismo en toda paciente con ETG. Un alto nivel de sospecha permitirá identificar a aquellas pacientes que cursen con hipertiroidismo, permitiendo así un diagnóstico y tratamiento oportuno.

Gestational trophoblastic disease (GTD) is a rare complication of pregnancy. GTD includes a group of proliferative lesions of trophoblastic tissue: partial and complete hydatidiform mole, choriocarcinoma, epithelioid trophoblastic tumor, and placental site trophoblastic tumor. The different types of GTD have in common the hypersecretion of human chorionic gonadotropin (hCG). HCG is a glycoprotein hormone with a similar structure to TSH. In physiological and pathological conditions hCG can stimulate thyroid function. GTD can present with hyperthyroidism, which can vary in intensity, from an asymptomatic presentation with mild alteration of thyroid hormones to a manifest hyperthyroidism. We present 3 clinical cases of patients with GTD thyrotoxicosis. All cases presented mild hyperthyroidism. Tachycardia was the only symptom in most cases. In all patients thyroid hormones return to normal after treatment of GTD. Conclusion: In patients with GTD the possibility of hyperthyroidism should be kept in mind. A high level of suspicion will allow to identifying patients with hyperthyroidism.

Mola invasiva. presentación de un caso / Mola invasiva. Apresentação de um caso / Invasive mole. Case presentation

Se presentó un caso de enfermedad trofoblástica tipo mola invasiva. El diagnóstico se sospechó con la ecografía del primer marcador genético, se realizaron dos legrados terapéuticos, el segundo de ellos, sugirió el diagnóstico de mola invasiva. Se realizó tratamiento quirúrgico (histerectomía total) con previa administración de quimioterapia con metotrexato sistémico. La biopsia confirmó el diagnóstico de mola invasiva. La mola invasiva es una de las formas de presentación de la enfermedad trofoblástica gestacional, es una condición infrecuente, en que la proliferación de células del trofoblasto y sincitiotrofoblasto penetran o incluso perforan la pared uterina, producen destrucción local pudiendo invadir el tejido parametrial y los vasos sanguíneos viajando dentro de estos, aunque no se han reportado verdaderas siembras metastásicas en otros órganos. La evolución clínica se realizó en consulta externa. Transcurrido dos años la evolución es satisfactoria, el tratamiento efectivo y bien tolerado por la paciente(AU).

A case of trophoblastic disease, of the invasive mole type was presented. The diagnosis was first suspected with the ultrasound of the first genetic marker. Two therapeutic curettages were performed, the second of which suggested the diagnosis of invasive mole. Surgical treatment (total hysterectomy) was performed with prior administration of chemotherapy with systemic methotrexate. The biopsy confirmed the diagnosis of invasive mole. Invasive mole is one of the forms of presentation of gestational trophoblastic disease. It is a rare condition in which the proliferation of trophoblast and syncytiotrophoblast cells penetrate or even perforate the uterine wall, produce local damage and can invade the parametrial tissue and blood vessels, traveling within these. True metastatic seeding in other organs has not been reported. The clinical evolution was carried out in an outpatient clinic. After two years the evolution is satisfactory, the treatment effective and well tolerated by the patient(AU).

Foi apresentado um caso de doença trofoblástica invasiva por mola. O diagnóstico foi suspeitado com a ultrassonografia do primeiro marcador genético, foram realizadas duas curetagens terapêuticas, sendo que a segunda sugeriu o diagnóstico de mola invasiva. O tratamento cirúrgico (histerectomia total) foi realizado com administração prévia de quimioterapia com metotrexato sistêmico. A biópsia confirmou o diagnóstico de mola invasiva. A mola invasiva é uma das formas de apresentação da doença trofoblástica gestacional, é uma condição infrequente, em que a proliferação de células trofoblásticas e sincitiotrofoblásticas penetram ou mesmo perfuram a parede uterina, produzem destruição local e podem invadir o tecido parametrial e vasos sanguíneos dos vasos. viajando dentro deles, embora verdadeira semeadura metastática em outros órgãos não tenha sido relatada. A evolução clínica foi realizada em ambulatório. Depois de dois anos, o a evolução é satisfatória, o tratamento é eficaz e bem tolerado pelo paciente(AU).

Clinical analysis of 10 cases of hydatidiform mole with coexistent intrauterine pregnancy / 中华围产医学杂志

Objective:To investigate the diagnosis and management of partial or complete hydatidiform mole with coexistent intrauterine pregnancy.Methods:Clinical data of 10 cases of hydatidiform mole with coexistent intrauterine pregnancy admitted to the Third Affiliated Hospital of Guangzhou Medical University, from September 2009 to May 2019 were retrospectively described.Results:(1) During the same period, 65 960 women were delivered at our hospital, and hydatidiform mole with coexistent intrauterine pregnancy was accounted for 1/6 596, among which complete hydatidiform mole and coexisting fetus (CHMCF) and partial hydatidiform mole and coexistent fetus (PHMCF) were found in four and six cases, respectively. The mean age of the ten patients were (30.9±4.1) years old, ranging from 26 to 35 years old, with 2.5 (1-4) times of pregnancies. Nine cases were identified at 22 +3 (12 +3-32 +3) gestational weeks and one at 9 + weeks. (2) Recurrent vaginal bleeding during pregnancy occurred in six cases, nausea and vomiting in three cases, and hyperthyroidism in mid- and late pregnancy in two cases. One patient developed preeclampsia and one case of severe mitral regurgitation with mild pulmonary hypertension. (3) In the 10 patients, the summit serum β -hCG level was 139 935 (16 990-546 033) U/L, and CHMCF and PHMCF patients were 212 500 (200 000-546 033) U/L and 60 768 (16 990-225 000) U/L, respectively. (4) The ultrasound results revealed a dark honeycomb area of the placenta in five cases, placental thickening in two cases, and vesicular placenta in one case. One case was found with bilateral giant luteinized ovarian cyst by ultrasound, multiple metastases in the left lower lobe of the lung by chest CT, multiple nodules in the pleural wall of the left lung by lung MRI, and CHMCF by pelvic MRI. In one case, ultrasound at 14 weeks of gestation showed interrupted fetal abdominal wall, visible mass, gastric bubble, liver, part of the intestinal echoes, and omphalocele. One case was found with embryo arrest. (5) The karyotype analysis of one case through amniocentesis was 46,XX with no anomalies, and chromosome microarray analysis was arr[hg19](1-22)×2. Prenatal diagnosis was refused in the remaining cases. (6) Among the ten patients, three were terminated by rivanol intra-amniotic injection, two received drug abortion, and uterine evacuation, and two with spontaneous abortion followed by curettage with a visible fetus and hydatidiform tissue. Total hysterectomy was performed in one patient due to partial invasion of the uterus by hydatidiform mole. One patient underwent a cesarean section on account of the left lower lung metastasis. One case developed preeclampsia at 33 +4 weeks of gestation and delivered two premature infants by cesarean section. Pathology examination found a complete and partial vesicular fetal mass in four and six cases, with P57 (－) and P57 (+), respectively. (7) During the follow-up, two women developed the persistent trophoblastic disease and received chemotherapy, while the remaining eight cases did not. Conclusions:When hydatidiform mole with coexistent intrauterine pregnancy is found, a timely differential diagnosis between CHMCF and PHMCF is needed. CHMCF is at a higher risk of abortion, intrauterine death, premature delivery, preeclampsia, and other maternal complications. Therefore, termination of CHMCF should be individualized. Most PHMCF patients have fetal malformation or fetal loss; thereby, timely termination is recommended.

Precision diagnosis of a full-term pregnancy with hydatidiform mole based on postnatal short tandem repeat DNA genotyping: a case report / 中华围产医学杂志

We describe a case of spontaneous conception following ovarian stimulation, in which a singleton pregnancy was revealed by ultrasound at 17 gestational weeks, with a multi-cystic "honeycomb" pattern in part of the placenta. With close monitoring, the patient delivered a healthy male neonate through cesarean section at 38 gestational weeks. The clinical findings, combined with ultrasound, laboratory, pathological, and immunohistochemistry examination, and short tandem repeat genotyping, confirmed a twin pregnancy consisting of a complete mole and coexisting fetus. No obvious abnormalities were found in the mother or the boy during a four-and-a-half-year's follow-up.

Clinical features and perinatal outcomes of 48 cases of pregnancy complicated with placental cystic lesions / 中华妇产科杂志

Objective:To investigate the clinical characteristics and perinatal outcomes of pregnancy with placental cystic lesions.Methods:A retrospective study was carried out on 48 pregnant women diagnosed as pregnancy complicated with placental cystic lesions from January 2000 to January 2020 at the Women′s Hospital, Zhejiang University School of Medicine. The clinical features, pathological diagnosis and perinatal outcome were analyzed.Results:The age of 48 cases was (30±5) years, and the diagnostic gestational week of ultrasound was (24±8) weeks. Twenty-five cases in which showed a cystic mass at the fetal surface were diagnosed as placental cyst. The live birth rate was 100% (25/25) and the premature birth rate was 20% (5/25). Twenty-three cases showed “honeycomb like” cystic echo. Cystic lesions of 10 cases were located in the uterine cavity connected with the margin of the normal placenta, and finally diagnosed as hydatidiform mole and coexisting fetus (HMCF). Six cases of HMCF terminated pregnancy, and the live birth rate was 4/10, the premature delivery rate was 2/4. Cystic lesions of 13 cases were located in the placenta substance, and finally diagnosed as 4 cases of placental mesenchymal dysplasia (PMD) and 9 cases of focal chorionic edema; the live birth rate was 6/13 and the premature delivery rate was 4/6. The median hCG was lower in focal chorionic edema group [80 kU/L (60-110 kU/L)] than in the groups of HMCF [240 kU/L (180-430 kU/L)] and PMD [360 kU/L (210-700 kU/L)], and the differences were statistically significant (all P<0.01). Conclusions:For pregnancy complicated with placental cystic lesions, prenatal ultrasound should be performed to evaluate the shape, location and blood flow of the lesions. Maternal serological examination and invasive prenatal diagnosis are helpful for prenatal diagnosis and treatment. Due to the difference of perinatal outcomes, maternal and fetal complications, individualized pregnancy management should be carried out.

Partial molar pregnancy with live fetus complicated by intrauterine growth restriction and severe preeclampsia. Case report and review of the literature / Mola parcial con feto vivo, complicado con restricción de crecimiento intrauterino y preeclamsia severa. Reporte de caso y revisión de la literatura

RESUMEN Objetivo: reportar un caso de mola parcial con feto vivo y realizar una revisión de la literatura sobre las complicaciones maternas y fetales asociadas a esta condición. Materiales y métodos: se presenta el reporte de un caso de mola parcial y feto vivo de 33 semanas, complicado por restricción de crecimiento intrauterino, oligoamnios y preeclampsia severa. Después de seguimiento del recién nacido a un año reportamos un resultado satisfactorio materno-fetal. Se realiza una búsqueda de la literatura en Medline vía PubMed, Lilacs, OVID, Uptodate y Google Scholar, con los siguientes términos MESH: "hiditadiform mole", "partial mole", "live fetus", "coexisting live fetus". Se seleccionaron estudios de series de caso y reportes de caso de gestantes con coexistencia de mola parcial y feto vivo al momento del diagnóstico, y se extrajo información sobre el pronóstico materno-fetal. Resultados: se identificaron inicialmente 129 títulos relacionados, de los cuales 29 cumplieron los criterios de inclusión, 4 artículos fueron excluidos por no obtener acceso al texto completo. Se analizaron 31 casos reportados, 9 casos terminaron en aborto, 8 terminaron en óbito o muerte perinatal y 14 (45 %) casos terminaron con un recién nacido vivo. La complicación materna más frecuente fue preeclampsia, en 6 (19,35 %) casos. Conclusión: la coexistencia de mola parcial con feto vivo presenta un riesgo alto de resultado perinatal adverso y preeclampsia. Se requiere más información sobre esta rara condición para determinar de mejor manera posibles intervenciones en los casos de fetos euploides y dar una adecuada asesoría en la práctica clínica, por lo que es importante el reporte de estos casos para tener suficiente evidencia sobre el comportamiento natural de la enfermedad.

ABSTRACT Objective: To report the case of a partial molar pregnancy with live fetus and conduct a review of the literature regarding maternal and fetal complications associated to this condition. Materials and methods: Case report of a partial mole with a 33 weeks live fetus complicated by intrauterine growth restriction, oligohydramnios and severe preeclampsia. We report satisfactory maternal and neonatal outcomes and 1-year follow-up. A search was conducted in the Medline via Pubmed, Lilacs, Ovid, Uptodate and Google Scholar databases using the following MESH terms: hiditadiform mole, partial mole, live fetus, coexisting live fetus. Case series and case reports of pregnant women with coexisting partial mole and live fetus at the time of diagnosis were selected and information regarding maternal and fetal prognosis was extracted Results: Initially, 129 related titles were identified. Of these, 29 met the inclusion criteria, and 4 articles were excluded due to failed access to the full text. Overall, 31 reported cases were included; 9 ended in miscarriage, 8 in fetal demise or perinatal death, and 14 (45 %) resulted in a live neonate. The most frequent maternal complication was preeclampsia in 6 (19.35 %) cases. Conclusion: The coexistence of a partial mole with a live fetus poses a high risk of adverse perinatal outcomes and preeclampsia. The volume of information regarding this rare condition must be increased in order to better determine potential interventions in cases of euploid fetuses and to provide adequate counseling in clinical practice. Therefore, reporting these cases is important to build sufficient evidence about the natural course of this condition.

Gestational Trophoblastic Diseases - A Clinicopathological Study

The term ‘gestational trophoblastic disease’, includes lesions, some of which are categorized as true neoplasms, and others that are representative of placentas that are malformed. It refers to various lesions that accompany the premalignant type, some of which are hydatidiform moles of the partial or the whole variety. The malignant type of lesions (GTD / GTN), include the following: choriocarcinoma, epithelioid trophoblastic tumour, placental site trophoblastic tumour, and invasive moles. METHODSA total number of thirty-four cases of GTD during the last two years at a tertiary care hospital was studied, relevant data was collected, and histological features studied. RESULTS79.41% of GTDs in the present study were complete mole, 58.82% of GTDs occurred in nullipara, 52.94% cases had GTDs seen in the third decade, 14.70% cases had history of previous GTD, 5.88% cases had history of previous abortion, 2.94% cases had a history of previous ectopic pregnancy, and case with choriocarcinoma had the highest HCG levels. In contrast, case with epithelioid trophoblastic tumour had the least HCG levels. CONCLUSIONSIn this particular study, it was found that most of the GTDs occurred in nulliparous women in their thirties and their occurrence increased with risk factors like a previous history of GTD, abortions, or ectopic pregnancy.
