Comments:
Borderline Brenner tumor (right half) with coexistent borderline mucinous tumor (left half). The Brenner tumor component consists of sharply-defined transitional epithelial nests in a fibromatous stroma. The mucinous borderline tumor shows cystic spaces with glandular and papillary structures lined by intestinal-type epithelium.
