RESUMEN
Los tumores de células germinales pertenecen al conjunto de neoplasias de origen no epitelial y que pueden presentar localización gonadal o extragonadal. Los teratomas son tumores compuestos por elementos derivados de dos o más capas embrionarias. Por lo común, su presentación es unilateral, aunque la presentación bilateral puede ser de hasta el 10% de los casos. La preservación ovárica es una técnica factible y útil, que permite tener una funcionalidad hormonal adecuada en pacientes en edad pediátrica que los presentan bilateralmente. Informamos dos casos clínicos en pacientes, una de 12 y la otra de 15 años de edad, con teratoma ovárico bilateral metacrónico, en las cuales se realizó salvamento del tejido ovárico. En la actualidad presentan niveles normales de producción hormonal, y para el futuro se espera la posibilidad de que sean fértiles gracias al tejido ovárico residual.
The germinal tumors belong to a group of non epithelial neoplasias which can have a gonadal or extragonadal localization. Teratomas are tumors which can have two or more embrionary layers its presentation is unilateral, but in 10% of the cases are bilateral. Ovary rescue is a feasible and useful technique in pediatric patients who present the bilateral form of the disease. In this paper we report two cases of pediatric patients, who developed a methacronic bilateral teratomas, one case of a 12 years old patient and the second one of a 15 years old girl, in both cases we performed ovarian tissue rescue. At the present time they have normal hormonal levels, and in the future they can probably be fertile thanks to the residual ovary tissue.
RESUMEN
Struma ovarii are specialized form of mature ovarian teratoma comprised predominantly of thyroid tissue (>50%). Most of the struma ovarii are benign; rarely can they undergo malignant transformation. Elevated CA-125 levels with benign struma ovarii have been seen in only 5 cases in literature. The association of malignant struma ovarii and high CA-125 levels with pseudo-Meig syndrome has been reported in only 2 cases in English literature. We describe a case of a 46-year-old multigravida who presented with an abdominal mass and raised CA-125 levels. Radiological investigations revealed bilateral cystic adnexal masses with ossified elements on left side suggesting a teratoma. Intraoperative frozen section and final pathology revealed bilateral teratoma with follicular variant of papillary thyroid carcinoma arising in the left ovary. To the best of our knowledge, this is the first case of malignant struma ovarii in combination with bilateral teratoma. The dilemmas related to preoperative diagnoses with elevated CA-125 levels, mimicking an epithelial ovarian neoplasm; intraoperative frozen section consultation; management and follow-up issues in this rare malignancy are discussed.
