Metastatic choriocarcinoma of the kidney in the absence of existing primary uterine tumor: A rare presentation.

Gestational choriocarcinomas are malignant neoplasms generally arising in the uterus in women of childbearing age. These are aggressive tumors with a high incidence of metastasis to vascular organs such as the lung, liver, and brain. Renal metastasis is extremely rare with low incidence rate and very few cases have been reported in literature. Hereby, we report a rare case of metastatic choriocarcinoma to the kidney in a 29-year-old female 10 years after resection of a hydatidiform mole. The histopathological diagnosis was made on a nephrectomy specimen. Pelvic and abdominal scan did not show any abnormal radiological findings. She was started on first-line chemotherapy and showed a complete response. In conclusion, gestational or primary nongestational choriocarcinomas should always be considered as a differential diagnosis in young females of reproductive age group presenting with flank abdominal pain, unexplained hematuria, and atypical renal tumor histology.

Ruptured ectopic molar pregnancy and ruptured uterine fibroid: a challenging rare diagnosis.

Although rare and unusual occurrences, a ruptured ectopic molar pregnancy (MP) and a ruptured uterine fibroid can lead to significant maternal morbidity and mortality. We present a unique case of these complications developing concurrently-resulting in the haemodynamic compromise of an otherwise healthy young female patient. The patient underwent a diagnostic laparoscopy which converted into a laparotomy, salpingectomy and myomectomy. Comprehensive histopathology confirmed the diagnosis of a ruptured ectopic complete MP and ruptured uterine fibroid. The patient recovered quickly within days. Prompt definitive management, conclusive histopathology and adequate follow-up were the hallmarks of this singular case. These key factors lead to the rare diagnosis of ruptured ectopic MP and uterine fibroid, prevention of adverse outcomes and provision of comprehensive patient care.

Molar pregnancy with a coexisting living fetus: a case series.

BACKGROUND: Coexistence of molar pregnancy with living fetus represents a challenge in diagnosis and treatment. The objective of this study to present the outcome of molar pregnancy with a coexisting living fetus who were managed in our University Hospital in the last 5 years. METHODS: We performed a retrospective analysis of patients who presented with molar pregnancy with a coexisting living fetus to our Gestational Trophoblastic Clinic, Mansoura University, Egypt from September, 2015 to August, 2020. Clinical characteristics of the patients, maternal complications as well as fetal outcome were recorded. The patients and their living babies were also followed up at least 6 months after delivery. RESULTS: Twelve pregnancies were analyzed. The mean maternal age was 26.0 (SD 4.1) years and the median parity was 1.0 (range 0-3). Duration of the pregnancies ranged from 14 to 36 weeks. The median serum hCG was 165,210.0 U/L (range 7662-1,200,000). Three fetuses survived outside the uterus (25%), one of them died after 5 months because of congenital malformations. Histologic diagnosis was available for 10 of 12 cases and revealed complete mole associated with a normal placenta in 6 cases (60%) and partial mole in 4 cases (40%). Maternal complications occurred in 6 cases (50%) with the most common was severe vaginal bleeding in 4 cases (33.3%). There was no significant association between B-hCG levels and maternal complications (P = 0.3). CONCLUSION: Maternal and fetal outcomes of molar pregnancy with a living fetus are poor. Counseling the patients for termination of pregnancy may be required. TRIAL REGISTRATION: The study was approved by Institutional Research Board (IRB), Faculty of Medicine, Mansoura University (number: R.21.10.1492).

Gestational trophoblastic neoplasm in a patient with end-stage renal failure (ESRF): the challenges and lessons learnt.

Gestational trophoblastic neoplasm (GTN) in end-stage renal failure (ESRF) has not been reported. We reported an unprecedented case of GTN in ESRF from an antecedent partial mole. She had total abdominal hysterectomy and bilateral salpingectomy following the diagnosis as the disease was confined to the uterus. A histopathological examination confirmed an invasive mole. Consequently, she received a total of four cycles of single-agent intravenous actinomycin D as she was at low risk. Despite initial response, her disease metastasised to her right kidney for which radiotherapy was given, followed by a total of 33 doses of weekly paclitaxel. She responded to the chemotherapy and currently remains in remission. The choice of chemotherapy and their side effects due to ESRF remain the main challenges in her management. Total hysterectomy should be considered as the first-line treatment for a hydatidiform mole to prevent GTN. A multidisciplinary approach is important to optimise the efficacy of the treatment with minimal compromise of her safety.

Life-threatening rupture of interstitial ectopic pregnancy: a rare presentation of metastatic invasive mole.

An invasive mole is an uncommon type of gestational trophoblastic disease, and if considering its implantation in an interstitial extrauterine location, we are facing a rarer condition.There are 14 cases described of interstitial ectopic gestational trophoblastic disease. As far as we know, we present the third case of invasive mole within interstitial location, in this case with pulmonary metastases.The diagnosis of an interstitial implantation is challenging. Our patient was initially diagnosed with an intrauterine hydatidiform molar pregnancy, and a uterine aspiration was performed. Two weeks later, she presented with haemodynamical instability due to a severe haemoperitoneum. A laparotomy was immediately performed and revealed a ruptured interstitial pregnancy with molar vesicle extrusion. Besides its rarity, we highlight the clinical presentation with hypovolaemic shock due to rupture of ectopic pregnancy in a young nulliparous woman, which required an emergent surgical approach with lifesaving purpose while preserving future fertility.

Ovarian Hyperstimulation Syndrome Complicating Spontaneous Molar Pregnancy: A Case Report and Review of the Literature.

BACKGROUND: Ovarian hyperstimulation syndrome (OHSS) is traditionally associated with fertility treatments and results in elevated human chorionic gonadotropin (ßhCG) levels and fluid shifts to extravascular compartments. Rarely, spontaneous pregnancies with significant ßhCG elevations, such as molar pregnancies, can give rise to OHSS. CASE: A 24-year-old woman was diagnosed as having a molar pregnancy at approximately 12 weeks gestation following spontaneous conception. Her initial ßhCG was over 1 million IU/L. There was no evidence of metastatic disease. She underwent an uncomplicated dilation and curettage. Three days later, she presented with chest pain, shortness of breath, and abdominal discomfort. Massively enlarged ovaries were identified with bilateral pleural effusions requiring repeated thoracentesis. CONCLUSION: This case demonstrates rare sequelae of molar pregnancy. Treatment is mainly supportive, and close observation is required to manage complications. In patients with extremely elevated ßhCG levels, clinicians must remain vigilant for signs suggesting OHSS, even following evacuation of the uterus.

Delivery management of a complete hydatidiform mole and co-existing viable fetus: A meta-analysis and systematic review.

OBJECTIVE: A twin pregnancy with a complete hydatidiform mole and co-existing viable fetus (CHMCF) is an exceedingly rare obstetric complication with few data related to perinatal treatment. This study determined the optimal timing of pregnancy termination and mode of delivery in women with CHMCF and a viable fetus. METHODS: The articles published involving CHMCF and a viable fetus from 1967 to 31 December 2020 in the PubMed and EMBASE databases were systematically reviewed. Observational cohort studies with three or more cases identified and data on delivery management were selected. The articles were analyzed independently for full text and the data were integrated. The timing of pregnancy termination and mode of delivery were calculated using Review Manager 5.4.1. RESULTS: There were 192 reports involving CHMCF; 209 cases had a viable fetus. According to the inclusion criteria, there were 6 case series, including 72 cases that were eligible for the analysis. The average rate of live births was 34.4%. The average duration of pregnancy was 34 weeks, ranging from 25 to 41 weeks. From 2000-2017 the live birth rate was increased year-after-year. Specifically, the live birth rate was16.7% in 2000, 33.3% in 2012, and 50% in 2017. Fifty-two cases (72.2%) had cesarean sections and 20 cases (27.8%) had vaginal deliveries. The incidence of gestational trophoblastic neoplasia was not significantly different between the two modes of delivery. CONCLUSIONS: Ideally, a twin pregnancy with a complete hydatidiform mole co-existing with a viable fetus is managed by an obstetrician, pediatrician, and oncologist. Appropriate timing of pregnancy termination and mode of delivery are related to the pregnancy outcome.

[Hyperthyroidism and an unexpected molar pregnancy]. / Hyperthyreoïdie en een onverwachte molazwangerschap.

BACKGROUND: A molar pregnancy is a rare complication of (non-viable) pregnancy and produces high levels of hCG-hormone. hCG has characteristics similar to TSH, and therefore (severe) hyperthyroidism can occur. The incidence of molar pregnancy is approximately 1 in 1000-1500 pregnancies. CASE DESCRIPTION: A 23-year-old woman had complaints of discomfort, nausea and vomiting. A urine pregnancy test was negative and laboratory tests showed a severe hyperthyroidism. After referral a molar pregnancy was diagnosed (hCG 1.7 million IU/L). She was treated by curettage. hCG levels insufficiently decreased in the following weeks, and gestational trophoblastic neoplasia was diagnosed. She needed several courses of methotrexate after which she completely recovered. CONCLUSION: Severe hyperthyreoidism can be caused by a molar pregnancy. A urine pregnancy test can be negative because of too high hCG-levels, also known as the hook effect. Early recognition and treatment are very important because of the risk of severe complications.

Hyperthyroidism secondary to a hydatidiform mole.

The case presented in the article is that of a 47-year-old female patient with hyperthyroidism induced by a hydatidiform mole. Attention was drawn to the necessity of preparing the patient for a procedure with drugs that stabilize the hormonal activity of the thyroid. The removal of the hydatidiform mole resulted in gradual normalization of thyroid hormone levels. The trophoblast has a hormonal activity, secrete hCG (human chorionic gonadotropin).The hCG partial structural homology causes affinity to the TSH (thyroid stimulating hormone) receptor. The higher the weight of the trophoblast, the higher the production and concentration of hCG in the blood. Therefore, gestational trophoblastic disease may be accompanied by hyperthyroidism. The problem is frequently described, however, due to the risk of developing thyroid storm, it cannot be overlooked [1].

Invasive mole presenting as a heavily bleeding vaginal lesion 3 weeks after uterine evacuation.

Gestational trophoblastic disease occurs in 1-3:1000 gestations worldwide. Up to one-fifth of complete hydatidiform moles undergo malignant transformation, with 2%-4% manifesting as metastatic disease. Of these, a third present with vaginal metastases, which can cause bleeding and discharge. We describe the case of a 49-year-old primiparous woman presenting with syncope and intense bleeding from an anterior vaginal lesion, 3 weeks after uterine evacuation for a presumed spontaneous abortion. A vaginal metastatic nodule was suspected; haemostasis was achieved with vaginal packing, precluding the need for surgical intervention. The patient was ultimately diagnosed with invasive mole with vaginal and lung metastases (stage III high-risk gestational trophoblastic neoplasia (GTN)) and started on multiple-agent chemotherapy. Two months later the lesion had regressed completely, and remission was reached 2 weeks later. Clinicians should consider the possibility of metastatic GTN with vaginal involvement whenever heavy vaginal bleeding follows a recent history of failed pregnancy.

Management of uterine rupture during molar pregnancy.

Gestational trophoblastic disease (GTD) is rare and encompasses several clinicopathologic forms from pre-malignant to malignant disorders. Clinical presentation is most of the time dominated by vaginal bleeding. Only few cases of uterine rupture during GTD have been reported in literature. We present the case of a female patient admitted to the hospital for hemorrhagic shock secondary to a uterine rupture due to an undiagnosed GTD. After an emergency laparoscopy, the patient underwent total hysterectomy with bilateral salpingectomy and bilateral ovarian cystectomy. Pulmonary metastasis were discovered on imaging after stagnation of the beta-hCG level. The surgical treatment was completed by 6 cycles of Methotrexate followed by 7 cycles of Actinomycine D with a good response.

A rare case of placental mesenchymal dysplasia - case report and literature review.

Described as a rare anomaly of the placenta, with a reported incidence of 0.02%, mesenchymal dysplasia is a benign condition characterized by placentomegaly, grape-like vesicles and by microscopic features resembling those of a molar pregnancy, such as hydropic villi, cistern formation and dysplastic blood vessels. We report a rare case of placental mesenchymal dysplasia diagnosed in a pregnancy with early symmetric fetal intrauterine growth restriction and a normal karyotype. Based on this case report, we discuss the particularities of this condition, emphasizing the ultrasonography and histopathological findings.

Histological Examination of Tissue Obtained in Early Pregnancy Loss.

Background It is a routine practice to send histological sample after surgical evacuation of early pregnancy loss. Objective This study was carried out to see the justification of regular histological study by carrying out the histological study of early pregnancy loss and to find the prevalence of gestational trophoblastic disease in early pregnancy loss. Method It was a descriptive prospective study, conducted in Nepal medical college teaching hospital from February to October 2020 in Obstetrics and Gynaecology department. Clinical data such as age, parity, gestational age and diagnosis were collected of 130 patient of early pregnancy loss. Then histological study were sent after surgical evacuation. Result Among the age group, 21-30 age group was maximum. (64.61%), more than half of the patient was primigravida (53.07%) and most of the cases were between 6 to 9 weeks of gestation. Incomplete abortions were maximum (43.07%), missed abortions 38.46%, blighted abortions 16.15%, enevitable abortions 1.53% and septic abortion was 0.76%. Among histological finding, 72.30% were product of conception, 15.38% of the cases had no product of conception, decidual tissue only in 6.92%, partial mole in one case (0.76%), complete mole in one case (0.76%) and hydrophic changes in one case (0.76%). The total cases of Gestational trophoblastic diseases (GTD) were 3(2.30%). Conclusion In our study we found 2.3% of cases of GTD, which was quite high in compare to Western word. So it is a good practice to do histological study of all cases of EPL in our country to detect GTD, determining cause for recurrent pregnancy loss and detecting unexpected fetal pathology.

Manejo clínico de la neoplasia trofoblástica gestacional: presentación de un caso / Clinical management of gestational trophoblastic neoplasia: presentation of a case

La enfermedad trofoblástica gestacional es una entidad poco frecuente que se produce por una proliferación anormal de la placenta. Engloba un diverso espectro de entidades histológicas, que conllevan a su vez diversas implicaciones clínicas. Unas son de carácter benigno (mola parcial y mola completa, placentomegalia, nódulo del sitio placentario) y otras de carácter maligno, estas últimas reciben en común la denominación de Neoplasia Tofoblástica Gestacional (NTG) y tienen un alto potencial de metastatización. Forman parte de las NTG: la mola invasiva, el tumor trofoblástico del sitio placentario, el tumor trofoblástico epitelioide y el coriocarcinoma gestacional. Lo más común es que la NTG debute tras la aparición de una gestación molar, pero también es posible que ocurra tras otro tipo de evento obstétrico como una gestación a término, o una gestación ectópica. Es pues de vital importancia realizar un correcto seguimiento tras evacuar una gestación molar, realizando una monitorización de los valores séricos de la BhcG y sospechando una enfermedad trofoblástica persistente ante los supuestos que posteriormente describiremos.La principal herramienta terapéutica para la NTG es el uso de la quimioterapia, aunque también se puede optar por la cirugía endeterminados casos. Habrá que valorar de modo individualizado en función de la histología, score pronóstico y deseos genésicos futuros de la paciente. Afortunadamente, la tasa de supervivencia y de curación de la NTG con un tratamiento y seguimiento adecuado es muy elevada. (AU)

Gestational trophoblastic disease is a rare entity that is caused by an abnormal proliferation of the placenta. It encompasses adiverse spectrum of histological entities, which carry various clinical implications. Some of them are benign (partial mole and complete mole, placentomegaly, placental site nodule) and others of a malignant nature, which are known as Gestational TrophoblasticNeoplasia (GTN) and have a high potential for metastasization. Are part of the GTN: invasive mole, trophoblastic tumor of theplacental site, trophoblastic tumor epithelioid and gestational choriocarcinoma. The most common is that NTG debuts after theappearance of a molar gestation, but it also may occur after another type of obstetric event such as a term gestation, or an ectopicgestation. It is therefore of vital importance to carry out a correct follow-up after evacuating a molar gestation, monitoring the serumvalues of BhcG and suspecting a persistent trophoblastic disease in the event that we will later describe. The main therapeutic toolfor NTG is the use of chemotherapy, although surgery can also be chosen in certain cases. It will be necessary to assess individuallyaccording to histology, prognostic score and future genetic desires of the patient. Fortunately, the survival and cure rate of NTG with proper treatment and follow-up is very high. (AU)

Spontaneous Ovarian Hyperstimulation Syndrome in a Partial Molar Pregnancy With Early Onset Severe Pre-eclampsia at 15 Weeks Gestation.

Ovarian hyperstimulation syndrome is a well-known entity in assisted reproductive technology. However, it is unusual for this entity to occur without any medications that stimulate follicle stimulating hormone. Herein, we describe a case where a partial molar pregnancy with high human chorionic gonadotropin promiscuously activated follicle stimulating hormone receptors has resulted in spontaneous ovarian hyperstimulation syndrome. There are only eight other cases documented per our literature search of ovarian hyperstimulation syndrome in molar gestations, and this is the third report in partial molar gestation. In our case, it is an unique development of severe early onset pre-eclampsia in the second trimester. Our goal is to discuss the nuances in management of this entity as well as to add the available body of research on this subject.
