Carcinoma of sigmoid colon presenting as abdominal wall abscess.

ABSTRACT

Abdominal wall abscess is a rare presentation of intra-abdominal disease. We describe a 69-year-old woman with a locally advanced carcinoma of the sigmoid colon presenting as abdominal wall abscess. The diagnosis was suggested by computed tomography of the abdomen. She was treated with resection of the tumor with closure of the rectal stump and proximal end colostomy. No adjuvant therapy was undertaken considering the extent of the disease. She survived for four months after the operation.
