Primary Ovarian Mutinous Cystic Tumor With Prominent Theca Cell Proliferation and Focal Granulosa Cell Tumor in its Stroma: Case Report, Literature Review, and Comparison With Sertoli-Leydig Cell Tumor With Heterologous Elements

摘要

A 73-year-old woman was found to have a 22cm unilateral multilocular mucinous cystic tumor of the ovary. Microscopic examination showed a routine appearance of the epithelial component, which ranged from benign to borderline to low-grade carcinoma. The stromal component was unusual because of a striking cellular theca cell component in the stroma, which, in turn, merged with a component of adult granulosa cell tumor. The "parent" neoplasm in this case and 3 other similar cases in the literature appears to be the mucinous neoplasm, in contrast with the other example of mucinous neoplasia associated with sex cord neoplasia, the Sertoli-Leydig cell tumor with heterologous elements, in which the "parent" neoplasm is likely the Sertoli-Leydig cell tumor.
