Immature cystic teratoma with contralateral mature cystic teratoma in a pediatric patient: Operative and ethical considerations to management

@#Immature cystic teratoma (IMCT) is a rare ovarian malignancy, usually presenting as a huge unilateral pelvoabdominal mass in the pediatric age. Even rarer is the occurrence of a concomitant contralateral mature cystic teratoma. Management issues include use of fertility sparing versus complete surgical staging, and the use of chemotherapy. Fortunately, IMCT carries a good prognosis, especially when diagnosed early. Chemotherapy is used only in higher stage disease and recurrence.

Metformin improves polycystic ovary syndrome and activates female germline stem cells in mice / 生理学报

Polycystic ovary syndrome (PCOS) is a common disease caused by complex endocrine and metabolic abnormalities in women of childbearing age. Metformin is the most widely used oral hypoglycemic drug in clinic. In recent years, metformin has been used in the treatment of PCOS, but its mechanism is not clear. In this study, we aimed to investigate the effect of metformin on PCOS and its mechanism through PCOS mouse model. Female C57BL/6J mice aged 4-5 weeks were intragastrically given letrozole (1 mg/kg daily) combined with a high-fat diet (HFD) for 21 days to establish the PCOS model. After modeling, metformin (200 mg/kg daily) was intragastrically administered. One month later, the body weight and oral glucose tolerance test (OGTT) were measured. Hematoxylin eosin (H&E) staining was used to detect the pathological changes of ovary. The serum levels of anti-Mullerian hormone (AMH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), E2 and testosterone (T) were measured by ELISA. The expression of DDX4/MVH was detected by immunohistochemistry. DDX4/MVH and PCNA were co-labeled by immunofluorescence. The protein levels of DDX4/MVH, PCNA, cyclin D2, AMPK and mTOR were detected by Western blot. The results showed that after metformin treatment, the body weights of PCOS mice were gradually returned to normal, glucose tolerance was significantly improved, serum E2 levels were increased, while AMH, LH, T levels and LH/FSH ratio were decreased. Ovarian polycystic lesions were reduced with reduced atresia follicles. Furthermore, the number of proliferative female germline stem cells (FGSCs) and levels of proliferation related proteins (PCNA, cyclin D2) were significantly increased, and the p-mTOR and p-AMPK levels were markedly up-regulated. These results suggest that metformin treatment not only improves hyperandrogenemia, glucose intolerance and polycystic ovarian lesions in PCOS, but also activates the function of FGSCs. The underlying mechanism may be related to the phosphorylation of AMPK and mTOR. These findings provide new evidence to use metformin in the treatment of PCOS and follicular development disorder.

Abdominal pain in the female patient: A case of concurrent acute appendicitis and infected ovarian cyst

Background: Abdominal pain is a common presentation in women of child bearing age. It has a broad diagnosis that includes disorders of the gastrointestinal, gynaecological, vascular, urogenital, and pulmonary systems. It may be caused by infections, inflammatory, anatomic or neoplastic processes. Its management varies by aetiology, and accurate diagnosis is key to avoiding inappropriate treatment. In some rare instances, acute appendicitis has been shown to occur simultaneously with a variety of gynaecologic diseases, which can add to the diagnostic dilemma. Method: We report a case of concurrent acute appendicitis and infected ovarian cyst in a 49 year old P6+4A6 who presented with recurrent abdominal pain for 4 years duration. Result: She had oophorectomy and appendicectomy. She did well post operatively and was discharged to outpatient department after stitches removal. Conclusion: Abdominal pain, being from various aetiology in women of child bearing age, detail history, thorough physical examination, and necessary imaging investigations need to be done to avoid misdiagnosis and inappropriate treatment.

Corpus luteum rupture mimicking acute appendicitis

Acute abdomen is a common presentation in women in the reproductive age. It may be caused by diverse conditions. The case below presented with classical signs and symptoms of appendicitis. Haemoperitoneum seen at laparotomy suggested a diagnosis of ectopic pregnancy .The diagnosis of ruptured corpus luteum cyst (RCLC) was made only after histology. The symptoms, signs and diagnosis of RCLC are discussed. The case highlights the need for circumspection in the diagnosis of the cause of acute abdomen. The current trend favours conservative management of RCLC thus the need for a high index of suspicion is emphasized to avoid unnecessary surgery.

Tumores anexiales incidentales en cirugía abdominal / Incidental adnexal tumors in abdominal surgery

La posibilidad de encontrar una neoplasia benigna o maligna del ovario, de forma inesperada durante una intervención quirúrgica abdominal, es una realidad para todos los especialistas en cirugía. Si bien en muchos casos se tratará de una lesión benigna, el riesgo de cáncer no debe subestimarse, ya que, por ejemplo, la ruptura intraoperatoria de una lesión quística maligna puede reestadificar a una paciente con cáncer de ovario del estadio IA al IC, con todas las consecuencias que esto implica, como la necesidad de requerir quimioterapia adyuvante y tener un peor pronóstico. Por otro lado, en mujeres premenopáusicas debe discutirse con la familia o la paciente (idealmente) el riesgo e implicaciones de la ooforectomía uni o bilateral, incluso si esto amerita dejar el quirófano para obtener el consentimiento, o posponer el procedimiento definitivo para un segundo tiempo. La consulta intraoperatoria a un ginecólogo, siempre que sea posible, se debe llevar a cabo con el fin de respaldar la conducta adoptada. Conocer el manejo adecuado de las masas anexiales encontradas de forma incidental durante una cirugía abdominal, es una prioridad para todos los cirujanos generales.

The possibility of finding a benign or malignant neoplasm of the ovary unexpectedly during abdominal surgery is a reality for all specialists in surgery. Although in many cases it will be a benign lesion, the risk of cancer should not be underestimated, since, for example, the intraoperative rupture of a malignant cystic lesion may well re-stage a patient with ovarian cancer from stage IA to IC, with the consequences that this implies, such as the need for adjuvant chemotherapy and a worse prognosis. On the other hand, in premenopausal women, the risk and implications of unilateral or bilateral oophorectomy should be discussed with the family or the patient (ideally), even if this implies leaving the operating room to obtain consent, or postponing the definitive procedure for a second time. Intraoperative consultation with a gynecologist, whenever possible, should be carried out in order to support the adopted behavior. Knowing the proper management of adnexal masses found incidentally during abdominal surgery is a priority for all general surgeons.

Discussion: The symptoms of intestinal duplications are nonspecific, recurrent abdominal pain and the presence of an abdominal mass are frequent. The preoperative diagnosis of intestinal duplications is occasional, it depends on the availability of imaging studies and clinical suspicion. The association of enterogenic cyst and renal agenesis is uncommon. Conclusion: A male patient is reported, with a pelvic mass of doubtful etiology and right renal agenesis, in whom an enterogenic cyst was diagnosed. The association of enterogenic cyst and renal agenesis is a rare malformation in adults(AU)

Principais causas ginecológicas de dor pélvica aguda em mulheres / Main gynecological causes of acute pelvic pain in women

Este trabalho buscou reunir dados essenciais sobre as etiologias de dor pélvica aguda, uma queixa constante nos serviços de emergências e ambulatórios de ginecologia, responsável por grande desconforto e impacto na qualidade de vida de pacientes mulheres. É uma condição laboriosa por causa de seu amplo espectro de causas, devendo ser abordada com cuidado e atenção pelo profissional médico, o qual deve considerar os diversos diagnósticos diferenciais, sendo a ultrassonografia o exame de maior importância para auxiliar em seu diagnóstico. As principais etiologias não obstétricas podem ser não ginecológicas e ginecológicas; essas últimas são divididas em anexiais e uterinas. Entre as causas ginecológicas, devem- -se investigar cistos ovarianos, torções anexiais, leiomiomas, doença inflamatória pélvica, abscesso tubo-ovariano, dismenorreia e complicações de dispositivos intrauterinos. A maioria das causas tem tratamento eficaz, com retorno da função do órgão e melhora da qualidade de vida, sem complicações, especialmente se diagnosticada precocemente.(AU)

The aim of this study was to gather important data on acute pelvic pain etiologies, a usual complaint in the emergency services and gynecology outpatient clinics, responsible for great discomfort and impact on quality of life in female patients. It is a laborious condition due to its wide spectrum of causes, which needs to be approached with attention by the physician, who must consider all the possible diagnoses, being the ultrasonography the most important exam to detect it. The main non-obstetric etiologies can be non-gynecological and gynecological, which are separated in adnexal and uterine causes. Among the gynecological causes, ovarian cysts, adnexal torsions, leiomyomas, pelvic inflammatory disease, ovarian tube abscess, dysmenorrhea and complications of intrauterine devices should be investigated. Most causes can be effectively treated, with return of organ function and improved quality of life, without complications, especially if diagnosed early.(AU)

Quiste gigante de ovario / Giant cyst of ovary

Introducción: Los tumores de gran tamaño han sido descritos a través de la historia, entre ellos los ginecológicos y los de ovario cuando pesan más de 12 kg constituyen una rareza médica. Las masas tumorales en hemiabdomen inferior son causas frecuentes de consulta en cirugía general. Dentro de estas, los quistes de ovarios son los que con más frecuencia se diagnostican. Objetivo: Describir el caso de un quiste gigante de ovario en una paciente que fue atendida en consulta de cirugia general por aumento de tamaño en el abdomen de varios años de evolución. Caso clínico: Se expone el caso de una paciente femenina, con antecedentes de salud, que acude al servicio de cirugía general por aumento de volumen del abdomen, progresivo, insidioso de 2 años de evolución. Se diagnostica masa quística dependiente de ovario y en el transoperatorio se constata una tumoración quística del ovario que en el análisis histopatológico informa un cistoadenoma seroso de ovario. Conclusión: Los tumores del ovario no son tan frecuentes como los del útero y los de la mama, pero constituyen el tercer grupo de tumores benignos y malignos de la mujer. Se presentó el caso por lo infrecuente que resulta, la escasa frecuencia de reporte de estos casos lo cual aporta conocimiento a la comunidad médica sobre el tema(AU)

Introduction: Large tumors have been described throughout history, including gynecological tumors, and ovarian tumors when they weigh more than 12 kg constitute a medical rarity. Tumor masses in lower hemiabdomen are frequent causes of consultation in general surgery. Within these, ovarian cysts are the most frequently diagnosed. Objective: To describe the case of a giant ovarian cyst in a patient who was treated in a general surgery consultation due to an increase in abdomen size of several years of evolution. Clinical case: The case of a female patient, with a history of health, which goes to the general surgery service due to an increase in abdomen volume, progressive, insidious of 2 years of evolution, is presented. Ovarian-dependent cystic mass is diagnosed and a cystic tumor of the ovary is found in the transoperative period, which in the histopathological analysis reports a serous ovarian cystadenoma. Conclusion: Ovarian tumors are not as frequent as those of the uterus and those of the breast, but they constitute the third group of benign and malignant tumors of women. The case was presented because of the infrequent result, the low frequency of reporting these cases, which brings knowledge to the medical community on the subject(AU)

Quiste gigante de ovario / Giant cyst of ovary

RESUMEN Históricamente, se describen como tumores de gran tamaño aquellos que pesan más de 12 Kg, entre ellos los ginecológicos y los de ovario; sobre todo antes del advenimiento de la ecografía y en poblaciones de mala situación socioeconómica y nivel cultural, como en los países del continente africano. Se presentó un caso de quiste gigante del ovario, en una paciente de 45 años de edad, que fue atendida en el Servicio de Cirugía General del Hospital Municipal de Bocoio, provincia de Benguela, República de Angola, en el año 2015. Se presentó por un aumento de tamaño del abdomen de varios años de evolución Se le diagnosticó una masa quística dependiente de ovario, por ultrasonografía por no contar con otro medio de diagnostico imagenologico. Se confirmó a través de una laparotomía exploradora la presencia de una tumoración quística gigante del ovario de 20 kg de peso. Esta patología es poco frecuente en la actualidad debido al desarrollo de la Cirugía y de los medios de diagnósticos que permiten su detección precoz. El estudio anatomopatológico ulterior informó un cistoadenoma seroso de ovario izquierdo. La evolución de la paciente fue favorable. Se consideró un caso interesante por lo infrecuente, la poca existencia de reporte de estos casos en la literatura, sobre todo en Cuba, lo que contribuye a aportar conocimientos a la comunidad médica (AU).

ABSTRACT Through the history those tumors weighting more than 12 kg have been described as great size tumors, among them the gynecological and the ovarian ones, especially before the appearance of the ultrasonography, and among populations of bad socio-economic situation and low cultural level, like in the countries of the African continent. The authors presented the case of a giant ovarian cyst in a patient aged 45 years, who assisted in the Service of General Surgery of the Municipal Hospital of Bocolo, province of Benguela, Republic of Angola, in 1915. She arrived to the consultation due to an increase of the abdominal size of several years of evolution. By ultrasonography because there was no other mean of imaging diagnosis, the diagnosis was an ovary-dependent cystic mass. Using laparoscopy it was confirmed the presence of a giant cystic tumor of the ovary of 20 kg weight. This disease is few frequent nowadays due to the development of Surgery and diagnostic means allowing a precocious detection. The subsequent anatomopathologic study informed a serous cystadenoma of the left ovary. The patient had a satisfactory evolution. The case was considered interesting given its infrequency, the scarce existence of reports of cases like this in the literature, especially in Cuba, contributing with knowledge for the medical community (AU).

Anti N-Methyl-D-Aspartate Receptor (NMDR) encephalitis in a 28-year old female with ovarian follicular cyst presenting with status epilepticus

@#Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a potentially fatal autoimmune condition where antibodies are produced and destroy NMDA receptors in the brain, thereby causing profound dysfunctional neurotransmission. This rare disease is often associated with a tumor, usually a teratoma. A 28-year-old female previously diagnosed with seizure disorder presented with chronic history of neuropsychiatric symptoms leading to status epilepticus on the day of confinement. Investigation showed the presence of anti-NMDAR antibodies both in serum and cerebrospinal fluid. A right ovarian cyst was noted on ultrasound. Methylprednisolone and immunoglobulin were given followed by surgical removal of the ovarian cyst. Histopathology result showed a follicular cyst. The patient was discharged improved, and remained asymptomatic and seizure free. Repeat serum NMDAR antibody test was negative. Early diagnosis and prompt treatment of patients with NMDA receptor encephalitis is lifesaving. Although mostly associated with an ovarian teratoma, the case reported a possible link between NMDAR encephalitis and benign ovarian cysts.

El papel de la enfermedad de von Willebrand en la hemorragia uterina anormal / Von Willebrand Disease in Abnormal Uterine Bleeding

RESUMEN La hemorragia uterina anormal es un término empleado para las alteraciones en la regularidad, duración y/o volumen de sangrado menstrual y es considerada una causa común de consulta médica y en ocasiones supone un reto diagnóstico para el médico tratante. Dentro del abordaje de la etiología de dicha patología, las coagulopatías afectan alrededor del 13 por ciento de las mujeres, y la más común es la enfermedad de von Willebrand. El objetivo de este trabajo fue realizar una revisión de la literatura científica actual sobre el papel que cumple la enfermedad de von Willebrand en la hemorragia uterina anormal. Esta es una patología hereditaria derivada de una deficiencia del factor von Willebrand encargado de la adhesión plaquetaria. La prevalencia de esta enfermedad puede ser baja, sin embargo, cuando se estudia la población de mujeres con menorragia, la frecuencia puede ir de 5 a 20 por ciento. Se han descrito diferentes problemas ginecológicos asociados a la enfermedad de von Willebrand, tales como menorragia, dismenorrea y una importante deficiencia de hierro asociada a esta, además de una mayor incidencia de quistes ováricos, endometriosis, hiperplasia endometrial y pólipos endometriales. La literatura actual sugiere que se realice tamizaje a aquellas mujeres con cuadro clínico sugestivo. Con respecto al tratamiento la literatura reporta el uso de ácido tranexámico y anticonceptivos orales, pero el que mayor utilidad ha demostrado es la desmopresina(AU)

ABSTRACT Abnormal uterine bleeding is a term used for alterations in the regularity, duration and / or volume of menstrual bleeding and it is considered a common cause of medical consultation; sometimes it is a diagnostic challenge for the treating physician. Within the aetiology approach of said pathology, coagulopathies affect around 13 percent of women, and the most common is von Willebrand disease. The objective is to review the current scientific literature on the influence of von Willebrand disease in abnormal uterine bleeding. This is an inherited pathology derived from a deficiency of the von Willebrand factor responsible for platelet adhesion. The prevalence of this disease may be low, however, when studying the population of women with menorrhagia, the frequency can range from 5 to 20 percent. Different gynecological problems associated with von Willebrand disease have been described, such as menorrhagia, dysmenorrhea and a significant iron deficiency associated with it, in addition to a higher incidence of ovarian cysts, endometriosis, endometrial hyperplasia and endometrial polyps. The current literature suggests that those women with suggestive clinical symptoms should be screened. Regarding treatment, the literature reports the use of tranexamic acid and oral contraceptives, nonetheless desmopressin has proven to be most useful(AU)

The impact on ovarian reserve of different hemostasis methods in laparoscopic cystectomy: a systematic review and meta-analysis / Impacto das diferentes técnicas hemostáticas empregadas na ooforoplastia videolaparoscópica sobre a reserva ovariana: revisão sistemática e meta-análise

Abstract Objective The objective of this review was to analyze the impact on ovarian reserve of the different hemostatic methods used during laparoscopic cystectomy. Data Sources The studies were identified by searching electronic databases (MEDLINE, Embase, Cochrane, LILACS) and scanning reference lists of articles. Methods of Study Selection We selected clinical trials that assessed the influence of hemostatic techniques on ovarian reserve in patients with ovarian cysts with benign sonographic appearance submitted to laparoscopic cystectomy by stripping technique. The included trials compared different laparoscopic hemostatic techniques: suture, bipolar electrocoagulation, ultrasonic energy and hemostatic sealants. The outcomes evaluated were level of serum anti-Mullerian hormone (AMH) and antral follicle count (AFC). The possibility of publication bias was evaluated by funnel plots. Tabulation, Integration and Results Twelve trials involving 1,047 patients were evaluated. Laparoscopic suturewas superior to bipolar coagulationwhen evaluating serum AMHand AFC, in the 1st, 3rd, 6th and 12thmonth after surgery. In the comparison between bipolar and hemostatic sealants, the results favored the use of hemostatic agents. The use of ultrasonic energy was not superior to the use of bipolar energy. Conclusion We recommend suture for hemostasis during laparoscopic cystectomy.

Resumo Objetivo O objetivo desta revisão foi comparar o impacto dos diferentes métodos hemostáticos na reserva ovariana durante a ooforoplastia laparoscópica. Fontes de Dados Os estudos foram identificados através da pesquisa de bases de dados eletrônicas (MEDLINE, Embase, Cochrane, LILACS) e listas de referência de artigos. Seleção dos estudos Selecionamos ensaios clínicos que avaliaram a influência das técnicas hemostáticas na reserva ovariana em pacientes com cistos ovarianos com aspecto ultrassonográfico benigno submetidos à ooforoplastia laparoscópica pela técnica de tração e contra-tração. Os estudos incluídos compararam as técnicas hemostáticas: sutura, energia bipolar, energia ultrassônica e selantes hemostáticos. Coleta de dados Os desfechos avaliados foram o hormônio antimülleriano e a contagem de folículos antrais. A possibilidade de viés de publicação foi avaliada por gráficos de funil. Síntese dos dados Doze estudos envolvendo 1.047 pacientes foram avaliados. A sutura foi superior à coagulação bipolar, e, na comparação entre selantes e energia bipolar, os resultados favoreceram o uso do primeiro grupo. O uso de energia ultrassônica não foi superior ao uso da energia bipolar. Conclusão Em conclusão, recomendamos a sutura para hemostasia durante a ooforoplastia laparoscópica.

Iatrogenic ureteral obstruction during transvaginal ocyte retrieval

ABSTRACT Transvaginal oocyte retrieval is a crucial step in assisted reproductive technology. Various complications may arise during this procedure. Ureteral injury is a rare, but a serious complication in gynecological practice. During oocyte retrieval, ureteral injuries, detachment and obstruction can be seen, though rare. In this study, we will present ureteral obstruction that develops secondary to small hematoma, which mimics ovarian cyst torsion or ruptured ovarian cyst.

The power of the Risk of Ovarian Malignancy Algorithm considering menopausal status: a comparison with CA 125 and HE4 / 부인종양

OBJECTIVE: To identify the power of tumor markers for predicting ovarian cancer according to menopausal status. METHODS: The medical records of 876 women with ovarian cysts were retrospectively reviewed. Cancer antigen 125 (CA 125), human epididymis protein 4 (HE4), and Risk of Ovarian Malignancy Algorithm (ROMA) were analyzed. Sensitivity, specificity, and the receiver operating characteristic (ROC) curve analyses of these tumor markers were evaluated. RESULTS: The sensitivity of ROMA was 66.7% and the specificity was 86.8% to detect ovarian malignancy. The patients were divided into 2 groups according to menopausal status: premenopause (n=532, 60.7%) and postmenopause (n=344, 39.3%). For diagnostic accuracy, ROMA was lower than HE4 in premenopausal women (82.7% vs. 91.4%) and lower than CA 125 in postmenopausal women (86.9% vs. 88.7%). The ROC curve analysis revealed that the power of ROMA was not significantly better than that of HE4 in premenopausal women (area under the curve [AUC], 0.731 vs. 0.732, p=0.832), and it was also not significantly better than that of CA 125 in postmenopausal women (AUC, 0.871 vs. 0.888, p=0.440). CONCLUSION: The discrimination power of tumor markers for ovarian cancer was different according to menopausal status. In predicting ovarian malignancy, ROMA was neither superior to HE4 in premenopausal women nor superior to CA 125 in postmenopausal women.

Laparoendoscopic Single Site Surgery for the Treatment of Huge Ovarian Cysts Using an Angiocatheter Needle

PURPOSE: The aim of this study was to evaluate the feasibility and safety of laparoendoscopic single site (LESS) surgery using an angiocatheter needle in patients with huge ovarian cysts (diameter ≥15 cm). MATERIALS AND METHODS: Thirty-one patients with huge ovarian cysts underwent LESS surgery using an angiocatheter needle between March 2011 and August 2016. An intra-umbilical vertical incision (1.5–2.0 cm) was made in the midline. After the cyst wall was punctured using an angiocatheter needle, the fluid contents were aspirated with a connected vacuum aspirator. After placing a Glove port in the umbilical incision, LESS surgery was performed using a rigid 0-degree, 5-mm laparoscope and conventional, rigid, straight laparoscopic instruments. Knife-in-bag morcellation was instituted for specimen collection. RESULTS: The median maximal diameter of ovarian cysts was 18 cm (range, 15–30 cm), the median operation time was 150 minutes (range, 80–520 minutes), and the median volume of blood loss was 100 mL (range, 20–800 mL). Three patients (9.7%) were diagnosed with malignant ovarian cancer using intraoperative frozen examination, and 1 patient was converted to laparotomy due to advanced disease. Thirty patients underwent LESS, and there was no need for an additional laparoscopic port. CONCLUSION: LESS surgery using an angiocatheter needle, with leaving only a small postoperative scar, was deemed feasible for the management of huge ovarian cysts.

Diagnóstico prenatal y manejo quirúrgico posnatal exitoso de quiste ovárico fetal / Prenatal diagnosis and successful postnatal surgical management of fetal ovarian cyst

Los quistes ováricos fetales son el tumor abdominal más frecuente en las recién nacidas. Es la tercera causa de quistes intrabdominales, después de los de sistemas renal y gastrointestinal. Se puede sospechar su presencia en la ecografía cuando se observa una tumoración de aspecto quístico de estructura regular localizado en la parte inferior y lateral del abdomen, del tracto intestinal o urinario en un feto femenino sin anomalías. Presentan complicaciones agudas y a largo plazo. La más frecuente es la torsión anexial que presenta dificultades diagnósticas en la etapa neonatal. El diagnóstico prenatal es fundamental para el manejo oportuno de las pacientes. Existen diferentes alternativas terapéuticas donde la cirugía mínimamente invasiva y conservadora juega un importante rol. El objetivo del trabajo es demostrar que el diagnóstico temprano de los tumores fetales interviene en el resultado exitoso. Se presenta el caso de una paciente de 37 años primigesta, a la que durante la evaluación ecográfica; se observó la presencia de una tumoración de apariencia blanda en la parte inferior derecha del abdomen correspondiente a un quiste ovárico fetal claramente identificado y separado de la vejiga fetal. La paciente fue sometida a cesárea en la que se obtuvo una recién nacida femenina. Dos días después, la neonata fue intervenida quirúrgicamente por mínimo acceso y se resolvió exitosamente gracias a un manejo multidisciplinario(AU)

Fetal ovarian cysts are the most frequent abdominal tumor in newborns. It is the third cause of intra-abdominal cysts, after those of renal and gastrointestinal systems. Its presence can be suspected on ultrasound when a cystic-like tumor of regular structure located in the lower and lateral part of the abdomen, intestinal tract or urinary tract is observed in a female fetus with no anomalies. They present acute and long-term complications. The most frequent is adnexal torsion that presents diagnostic difficulties in the neonatal stage. Prenatal diagnosis is essential for the timely management. There are different therapeutic alternatives where minimally invasive and conservative surgery are important. The objective of the work is to demonstrate that the early diagnosis of fetal tumors intervenes in the successful outcome. We present the case of a 37-year-old primiparous patient, who had a soft-appearing tumor in the lower right part of the abdomen observed by ultrasound. This corresponded to a clearly identified fetal ovarian cyst and it was separated from the fetal bladder. The patient underwent cesarean section in which a female newborn was obtained. Two days later, the neonatal was minimal-access surgically treated successfully thanks to multidisciplinary management(AU)

Tumores ováricos en niñas y adolescentes / Ovarían masses in infant-juvenile age

Introducción. El tratamiento quirúrgico adecuado para las pacientes pediátricas con lesiones ováricas es heterogéneo, y en las niñas es conveniente conservar los ovarios. El objetivo de este estudio es analizar los hallazgos relacionados con un grupo de pacientes a las que se operó por lesiones ováricas. Pacientes y métodos. Un estudio retrospectivo realizado durante 13 años con 56 pacientes menores de 17 años. Estas pacientes se dividieron en 3 grupos según el diagnóstico de patología ovárica: 25 tenían lesiones funcionales (quistes y torsión), 18 tenían lesiones ováricas epiteliales y 13 tenían tumores germinales. Se comparó a estos tres grupos en términos de menarquia, torsión, edad, duración, tamaño, dolor, tumor, vómitos, menstruación irregular, ubicación y tipo de operación. Resultados. Enestosgrupos,fueronmásfrecuentes los quistes foliculares, los cistoadenomas serosos y los teratomas. La media de edad de las pacientes fue de 12,18 ± 4,84 años. Los síntomas y signos más frecuentes fueron dolor (85,7%) e hinchazón (37,5%) en la región abdominopélvica. Se observó torsión en 21 pacientes (37,5%); la media del tamaño del tumor fue de 10,46 ± 6,55 cm. Se realizó una salpingoovariectomía (SO, por sus siglas en inglés) en 38 pacientes y una resección del quiste (CE, por sus siglas en inglés) en 18 pacientes. Se observaron más casos de torsión en las pacientes premenárquicas que en las menárquicas y en el grupo de lesiones funcionales. Se realizaron más resecciones quirúrgicas en el grupo de lesiones funcionales, y más SO en los grupos de lesiones epiteliales y tumores germinales. Conclusión. Se considera que la torsión y las patologías ováricas funcionales son frecuentes en la edad premenstrual, y las lesiones malignas son muy raras en todos los grupos etarios, por lo que se recomienda preservar la fertilidad en la cirugía.

Introduction. The appropraite surgical treatment to pediatric patients with ovarian lesions are heterogeneous and ovarian preservation is desirable in children. The aim of this study is to the discuss findings related to a set of patients who were operated on for ovarian lesions. Patients and methods. A retrospective study carried out in 13 years on 56 patients under the age of 17. These patients were divided into 3 groups according to ovarian pathologic diagnosis: 25 with functional (cyts and torsion), 18 with epithelial ovarian lesions and 13 with germ cell tumours. These three groups were compared in terms of menarche, torsion, age, duration, size, pain, mass, vomiting, irregular menstruation, location and operation type. Results. Follicle cysts, serous cyst adenomas and teratomas were the most common in these groups. The mean age of the patients was 12.18+4.84 years. The most common symptoms and signs were abdominal-pelvic pain (85.7%) and swelling(37.5%). Torsion was seen in 21 patients (37.5%), mean mass size was found to be 10.46+6.55 cm. A salpingo-oophorectomy (SO) was performed in 38 patients and cyst excision (CE) was performed in 18 patients. In premenarcheal cases, torsion was seen more in menarcheal cases and in the functional lesion group. CE was performed more often in the functional and t SO was performed often in the epithelial and germ cells groups. Conclusion. Torsion and functional ovarian pathologies are thought to be common in premenstrual ages and malign lesions are very rare in all age groups so we recommend ovarian protective surgery should be preferred.
