Bilateral malignant Brenner tumor of the ovary

Malignant Brenner tumor: Two case reports

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.

•

Two rare cases of malignant Brenner tumor (MBT) are reported.

•

Surgical resection remains the cornerstone for diagnosis and treatment.

•

Delineating between MBT and transitional cell carcinoma histologically remains a challenge.

•

The addition of adjuvant chemotherapy and radiation to observation alone remains controversial.

Malignant Brenner tumor of the ovary

Three cases of stage III malignant Brenner tumor of the ovary in which chemotherapy or radiotherapy favorably altered the clinical courses are reported, and the literature is reviewed.
