A rare presentation of perforated carcinoma of colon as an anterior abdominal wall abscess—a case report and review of literature

Colorectal cancer progresses without any symptoms early on or those clinical symptoms are very discrete and so are undetected for long periods of time. Complicated colorectal carcinoma has several symptoms, the most common being bleeding and obstruction. Occasionally, it will cause perforation, which carries a worse prognosis. It is rare for a carcinoma colon to present as abscess of the anterior abdominal wall that forms as a result of direct invasion and perforation of the colon by cancer. We hereby report an unusual case of perforated colon carcinoma presented as an abscess infiltrating the abdominal wall.
