    Colorectal cancer (CRC) is the most common cancer of gastrointestinal (GI) tract, third most common cancer with a prevalence of 13% and the second most frequent cause of cancer mortality among men and women worldwide. Locally advanced colorectal cancers account for 5%- 22% of all colorectal carcinomas (CRCs) and are a subgroup of colorectal tumors that invade adjacent organs without distant metastases. Although anterior abdominal wall abscesses due to direct invasion of colonic tumors are very rare but have been described and according to the largest review by White et al consists of nine cases collected over a 32-year, have an overall incidence of approximately 1 per 1700 colorecal carcinoma cases. Here we describe a case of sigmoid carcinoma with abnormal presentation due to tumor perforation and right lower quadrant abdominal wall abscess formation. Our purpose is to draw attention to this rare presentation and to indicate that such patients are potentially curable especially under purposeful screening programs.
