Ovarian Combined Brenner Tumor, Mucinous Cystadenoma And Struma Ovarii: First Report Of A Rare Combination

Brenner tumors are uncommon ovarian neoplasms which occasionally occur in combination with a mucinous tumor. Rarely, the combination of Brenner tumor and thyroid tissue (struma ovarii) has been reported. We report an ovarian neoplasm with components of Brenner tumor, mucinous cystadenoma and struma ovarii. As far as we are aware, this combination has not been previously reported. We speculate on the possible histogenesis of this combination of elements.
