Abstract
Introduction
Multiple primary tumors identified pre-operatively, intraoperatively or a second tumor diagnosed within 6 months of resection of primary tumor are termed as synchronous tumor. Collision tumors are rare neoplasms in which two distinct tumors co-exists together in the same organ but are histologically different with no histological intermixing. We are presenting a case report of a very rare combination of synchronous adenocarcinoma of colon coexisting with a collision ovarian tumour i.e. fibroma with serous cystadenoma. To the best of our knowledge, there are no reported cases of synchronous tumor of colon with collision tumor of ovary reported in literature by far.
Case Report
A 60 years oldwoman presented with left sided abdominal mass with altered bowel habits and bleeding per rectum. Computed tomography (CT) scan showed a densely adhered solid cystic mass in the left ovary with a colonic mass. A clinical diagnosis of colon carcinoma with metastasis to left ovary or vice versa was made. On histopathological examination, final diagnosis of fibroma and serous cystadenoma of left ovary with adenocarcinoma colon was made.
Conclusion
We hope that this case helps to increase surgeon’s awareness of the adnexal masses they may come across during surgery.
