Two unusual and rare forms of Brenner tumor are reported and the literatures are reviewed. The one, "proliferating" Brenner tumor, morphologically resembling low grade papillary transitional cell carcinoma of urinary bladder and regarded as a third variant intermediate between the benign and malignant forms; the other, malignant Brenner tumor of right ovary, corresponding to grade III transitional cell carcinoma of urinarybladder with areas of invasive squamous cell carcinoma and benign Brenner tumor of left ovary, combined with bilateral cystic teratomas. These tumors give additional support to the concept that Brenner tumors are composted of epithelium of urinary tract(urothelial) type.
