Background: Colorectal cancer progresses without any symptoms early on, or those clinical symptoms are very discrete and so are undetected for long periods of time. The case reported is an unusual presentation of colorectal cancer. Case Report:A 60 year old man presented with right sided abdominal swelling. On examination, a well-defi ned, fi rm, tender swelling was noted. Computed tomography confi rmed the presence of a mass arising from the right colon with infi ltration of the right lateral abdominal wall and adjacent collection. An exploratory laparotomy with drainage of the subcutaneous abscess, resection of ascending colon, and ileotransverse colon anastomosis was performed. Conclusion:A differential diagnosis of carcinoma colon should be considered when an elderly patient presents with abdominal wall abscess accompanied by altered bowel habits or per rectal bleeding, even if there are no other signifi cant clinical symptoms and a thorough investigative work up is required to confi rm the diagnosis, to avoid untimely delay in treatment, and reduce mortality.
