A rare clinical case of synchronous colorectal cancer, affecting the transverse colon

Synchronous colorectal cancer is a rare condition, which presents with the simultaneous development of more than one primary carcinoma and affects different segments of the colon and rectum. The incidence of this disease is about 3.5 per cent of all carcinomas of the colon and rectum and more often affected men. Adenocarcinoma is the most common histological type for synchronous colorectal cancer. We present a rare clinical case of a 62-year-old woman with synchronous colorectal carcinoma, located in the transverse and sigmoid colon and verified histologically by colonoscopy.
