Luteoma del embarazo. Reporte de caso / Luteoma of pregnancy. A case report

Luteoma of pregnancy is an infrequent non-neoplastic pathology of the ovary. It is usually an incidental finding during the evaluation of a pregnant patient in the third trimester or during a cesarean section. Occasionally, it may raise suspicion of cancer, resulting in unnecessary surgical resection of the ovary. We present the case of a 34-year-old woman who was in her third pregnancy and during the cesarean section, a 9 cm tumor of the right ovary was incidentally found and resected. The histological study was compatible with luteoma of pregnancy.

El luteoma del embarazo es una patología no neoplásica del ovario, de incidencia poco frecuente. Suele presentarse como hallazgo incidental durante la evaluación de una paciente embarazada en el tercer trimestre o en el momento del acto quirúrgico de una cesárea. En ocasiones, puede llevar a sospechar una neoplasia maligna, derivando así en una resección quirúrgica innecesaria del ovario. Presentamos el caso de una mujer de 34 años que cursaba su tercera gestación y a quien, durante la cesárea, se le halló una tumoración ovárica derecha de 9 cm de diámetro que fue resecada. El estudio histológico fue compatible con luteoma del embarazo.

Luteoma gestacional não virilizante simulando neoplasia ovariana / Pregnancy luteoma without virilization mistaken by an ovarian tumor

Objetivo: descrever um caso de ooforectomia em paciente com luteoma gestacional, um pseudotumor ovariano relacionado a uma resposta exagerada do estroma ovariano aos hormônios da gravidez que regride após o parto. Relato do caso: mulher de 42 anos, em sua terceira gestação, evoluiu sem intercorrências. Durante a realização de cesariana, observou-se a existência de tumoração ovariana bilateral, sendo realizada ooforectomia. A análise histopatológica demonstrou-se tratar-se de um luteoma gestacional. Considerações finais: por não constituir um tumor verdadeiro e pela tendência à regressão no pós-parto, readquirindo as dimensões normais, deve-se avaliar com cautela a realização de ooforectomias em pacientes gestantes que apresentem aumento das dimensões ovarianas.

Purpose:to report a case of pregnancy luteoma, an ovarian pseudotumors usually diagnosed during cesarian section or at postdelivery tubal ligation. After delivery the ovary size returns to normal in a few weeks. Case Report: A 46 year old female,(G 3, P 2) without complains. During cesarian section It was noticed an increase of the ovarian size, the approch was bilateral ooforectomy.The histhopathological diagnostic was pregnancy luteoma .Final Considerations: being just a pseudotumor that decrease after delivery the surgeon must remember this nosological entity, that is easily mistaken by true ovarian tumors, and try to avoid an ooforectomy.

Pregnancy Luteoma of the Ovary in a Primiparous Woman: A case report

Pregnancy luteoma is composed of a single or multiple nodules of large lutenized cells that develop during pregnancy but involute during the puerperium. This lesion is usually an incidental finding at the time of cesarean section or postpartum tubal ligation. Microscopically, this tumor is difficult to be differentiated from various types of sex-cord stromal tumors including Leydig cell tumor, luteinized thecoma, adult or juvenile granulosa cell tumors with luteinization, and lipoid cell tumor. We report a case of pregnancy luteoma in a 34-year-old primipara without virilizing symptoms at the time of cesarean section in the right ovary. The mass measured 5x4.5x3.5 cm and 60 gm in weight. The cut surface was homogeneously yellow-orange with mulitple hemorrhagic spots. Microscopically, the tumor revealed solid, trabecular, or microcystic pattern of large granular eosinophilic luteinized cells and somewhat large nuclei with prominent nucleoli. Differentiation from Leydig cell tumor and juvenile granulosa cell tumor was difficult in this case.
