Collision tumor of ovary: A rare entity

Abstract

Collision tumors are composed of two histologically distinct neoplasms in the same organ without intermixture of cell types. The co-occurrence of a serous adenocarcinoma with a mature cystic teratoma is very rare. We present here the case of a 48 years married female with bilateral high grade serous carcinoma of the ovary with left sided mature cystic teratoma.
