Abstract

Though collision tumors have been reported earlier like serous cystadenoma and mature cystic teratoma, combination of mucinous cystadenoma and adult granulosa cell tumor is rarely reported in the literature. Collision tumors lack the histological cellular intermingling which is seen in composite tumors. Both involve two morphologically and immunohistochemically distinct neoplasms coexisting within a single organ. Mucinous cystadenoma is a benign cystic surface epithelial tumor of ovary. Granulosa cell tumor(GCT) is a low grade malignancy arising from sex cord stromal cells of ovary and need a close follow up for recurrences which may be late. Here we present a case of 50 year old female who presented with lower abdominal pain. Patient underwent staging laporotomy and ovarian specimen sent for histopathological examination, where it was diagnosed as mucinous cystadenoma coexisting with adult granulosa cell tumor. This case report emphasis upon the fact that multiloculated cyst have to be extensively examined grossly, so as not to miss any solid component which might have a bearing on prognosis of the patient. Here the association of mucinous cystadenoma and granulosa cell tumor need close follow up of patient.
