ABSTRACT
Gynandroblastoma is an extremely rare sex cord-stromal tumor with both female (granulosa cell tumor) and male (Sertoli-Leydig cell tumor) elements. Juvenile granulosa cell tumors are also very rare and are so named because they usually occur in children and adolescents. A 71-year-old woman with right upper quadrant abdominal pain visited our hospital. Pelvic computed tomography showed a large multilocular cystic mass, suspected to be of ovarian origin. We performed a total abdominal hysterectomy (total abdominal hysterectomy was performed) with bilateral salpingo-oophorectomy. A 13-cm multilocular cystic mass with serous fluid was observed in her right ovary. Upon microscopic examination, the solid component of the mass showed both Sertoli-Leydig cell and juvenile granulosa cell differentiation, which we diagnosed as gynandroblastoma. Gynandroblastoma with a juvenile granulosa cell tumor component is extremely rare and, until now, only six cases have been reported in the English literature. We report the first gynandroblastoma with a juvenile granulosa cell tumor component diagnosed in an elderly patient, along with a literature review.

Los ginandroblastomas son tumores del ovario extremadamente raros, los cuales comparten componentes de células de la granulosa y de células de Sertoli/Leydig. Se describe un caso de una niña de 12 años, quien presenta hemorragia uterina anormal y sensación de masa intraabdominal de crecimiento progresivo asociado a menorragia, niveles de CA-125 en 60,4 UI/mL y estudios de extensión que reportan masa quística en ovario izquierdo, manejada con ooforectomía. El estudio anatomopatológico muestra un tumor multiloculado lleno de material seroso, abundantes cuerpos de Call-Exner y 45% de células de Sertoli/Leydig. La inmunohistoquímica reveló inmunorreactividad para inhibina, calretinina y pCK, mientras que los marcadores CD99 y AE1/AE3 fueron negativos. Se trata del primer reporte de caso sobre un ginandroblastoma multiloculado, negativo para CD99 en una niña de 12 años, estudio que plantea un abordaje sistemático para los tumores de las células de los cordones sexuales.
The ginandroblastoma is an extremely rare ovarian tumor which shows components of granulosa cells and Sertoli/Leydig cells. We describe a case of a twelve-years-old girl who presented abnormal uterine bleeding and progressively growing intra- abdominal mass associated with menorrhagia, CA-125 60.4 UI/mL and extension studies reporting cystic mass in the left ovary. She underwent oophorectomy. Pathological study shows a multilocular tumor filled with serous material. Many Call-Exner bodies were observed in the histopathological analysis, 45% of Sertoli/Leydig cells. Immunohistochemistry was reactive for inhibin, calretinin and pCK while AE1/AE3 and CD99 markers were negative. This is the first case report about a multiloculated gynandroblastoma, negative for CD99 in a 12-years-old girl. Thus, the study of this clinical case represents a systematic approach for tumors of the sex cord cells.
