ABSTRACT
Contexto: Luteoma é neoplasia rara e benigna do ovário, específica da gravidez. Considera-se que seja causada por efeitos hormonais, principalmente da gonadotrofina coriônica. Objetivo: Analisar artigos selecionados sobre luteoma da gravidez e realizar revisão bibliográfica a partir dessas publicações. Desenho: A busca dos artigos foi realizada por meio da plataforma PubMed. Procedeu-se uma busca aos descritores da doença e seu correspondente em inglês (luteoma) no portal da BVSalud. Métodos: Consistiu em revisão bibliográfica, onde foram utilizados artigos publicados de 1972 até 2022. Resultados: A origem celular dos luteomas ainda é desconhecida, mas considera-se que tal processo ocorra devido a uma reação hiperplásica à gravidez, visto que o efeito de virilização regride após o parto. Discussão: Sendo pouco diagnosticado, tendo menos de 200 casos reportados, são geralmente achados durante parto cesáreo ou durante ligadura tubária no pós-parto. Seu aparecimento está relacionado a fatores hormonais da gravidez e hiperplasia ocasionada pela luteinização das células estromais. Os efeitos do luteoma gravídico no organismo estão relacionados, além da virilização da paciente e do feto, com o surgimento da síndrome do ovário policístico e diabetes. Conclusões: Tendo baixa incidência, o luteoma gravídico pode se apresentar como desafio para seu diagnóstico adequado. O diagnóstico precoce permitirá o tratamento adequado, evitando-se efeitos indesejáveis, virilizantes, para a gestante e para o nascituro. É fundamental o preparo dos profissionais de saúde para o diagnóstico e tratamento do luteoma gravídico.

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.

A 6-year-old female nulliparous Dutch Rabbit (Oryctolagus cuniculus) was presented in shock status with a history of abdominal distention, inappetance, lethargy, polydipsia, diarrhea and weight loss since 2 weeks ago. There was no breeding history. Radiographic survey showed increased soft tissue opacity dorsal to the urinary bladder and ventral to the colon on the lateral view consistent with uteromegaly and severe intestinal distention resembling intussusceptions. Conservative treatment was failed and the animal died. In necropsy, ileocecal intussusception was noted as the main death factor. Thickened uterine endometrium in both horns was observed and the uterus was filled with mucoid fluid. Both ovaries were multilobulated and distended. On the other hand, a small cyst sized 1.5 × 2.5 cm was diagnosed on the liver surface. Several samples were obtained from lesions for histopathological evaluation. Histopathologically, dilated cystic glands of variable size lined by densely packed epithelium and hyperplasia of the endometrium resulting in irregular folds or papillar projection into the lumen were evident and the sections of ovaries revealed ovarian luteoma that composed of polyhedral cells with pale stained vacuolated cytoplasm, centrally located nuclei with distinct cytoplasmic borders and the cytoplasm of cells contain lipid droplet. The occurrence of biliary cyst adenoma was confirmed by microscopic examination of the mass that composed of multicystic space in different sizes lined by flattened to cuboidal biliary epithelium with papillary projections. These cysts were seperated by variable amount of connective tissue. The lack of postmortem investigations in aged rabbits reduced the incidence of neoplastic disease diagnosis in this species. Whereas uterine adenecarcinoma and lymphosarcoma were commonly reported in rabbits, luteoma and biliary cyst adenoma that are well described in this case report were uncommon in rabbit medicine.
ABSTRACT
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 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.
