Tumores de colisión ováricos asociados con teratoma

Collision tumors represent the coexistence of 2 adjacent but histologically distinct tumors without histologic admixture in an organ. In gynecology, collision tumors in the uterus (corpus and cervix) and ovary have been described. We report a case of ovarian mucinous cystadenoma coexisting with a benign cystic teratoma.
