Malignant Brenner tumor: Two case reports

Abstract

Malignant Brenner tumor (MBT) is a rare ovarian tumor that, given the infrequency of the disease, has not been well documented in the literature. Diagnosing MBT both radiographically and histologically remains a challenge. We report two cases of ovarian MBT, detailing the clinical presentation, radiographic characteristics, and histologic findings with supplementary imaging. Our cases demonstrate the pathologic challenge of histologically diagnosing MBT versus other Brenner tumors and transitional cell carcinoma (TCC) of the ovary.
