Sertoliform endometrioid carcinoma of the right ovary.

Our 47-year-old patient presented with virilizing symptoms that were rapidly progressing, which raises the suspicion of an underlying androgen secreting neoplasm. Sertoliform endometrioid carcinoma (SEC) is an extremely rare variant of endometrioid carcinomas and tend to present at an earlier stage as compared to most endometrioid carcinomas of the ovary. Recognition of SEC in virilizing patients is important as it is a well-differentiated, low-grade malignancy with a good prognosis when confined to the ovary.
