Abstract PDF: Brenner tumors constitute about l.5~2.5% of all primary ovarian neoplasms and are almost always benign. It appears to derive from the surface epithelium of the ovary which undergoes metap1asia to form the urothelial-like components. we experienced a case of malignant Brenner tumor with adenocarcinoma and squamous cell carcinoma patterns in a 57-year-old woman. It was partly cystic tumor and contained a 4cm-sized gray yellow, lobulated or papillary solid mass, projecting from the cystic wall. Ultrastructurally, the solid mass was composed of malignant urothelial-like cells with focal glandular differentiation.
