A case of sigmoid colon cancer with abdominal wall abscess]

A 63-year-old man was admitted for an abdominal mass. Computed tomography revealed an abscess (21 × 20 cm) in the abdominal wall and a tumor in the sigmoid colon. Thus, cancer of the sigmoid colon complicated by an abscess of the abdominal wall was diagnosed. The abscess was drained and transverse colostomy was performed with curative intent. After the intervention, chemotherapy (XELOX×3) was administered. Three months later, sigmoidectomy was performed and the stoma was closed. Macroscopic and microscopic examination of the resected specimen detected no remnants of cancer. In patients with advanced colon cancer and abdominal wall involvement, a two-stage operation and preoperative chemotherapy may be considered essential when curative resection is performed.
