Mucinous Cystadenocarcinoma Co-Existing with Mature Cystic Teratoma : A Rare Case Report

Co-existence of rnucinous cystadenocarcinoma with mature cystic teratoma in the same ovary is very rare. We report a case in a 48-year-old female who presented with left abdominal mass. CT scan revealed a heterogeneous enhancing left ovarian mass lesion. Clinical diagnosis of complex ovarian cyst was made, later underwent laparotomy and histologically diagnosed as mucinous oystadenocarcinoma (grade 2) co-existing with benign cystic teratoma, stage la (FIGO) of the left ovary. Six months after surgery, the patient is doing well without any recurrence or metastasis. Hence, histopathological examination plays a significant role in accurate diagnosis and management of the patient, So, we should be aware of these rare co-existent tumours and meticulous dissection should be done to look for any synchronous tumours or malignant areas; since management and prognosis will vary significantly depending upon the microscopic type and stage.
