A 70-year-old man presented to our hospital with a left lower abdominal tumor. We performed drainage of the abscess, which was revealed in the abdominal wall on computed tomography. Colonoscopy showed a type 2 tumor at the sigmoid colon with a stenosis, which was diagnosed as well-differentiated adenocarcinoma based on the pathological examination. We performed a sigmoidectomy with abdominal wall resection after bowel decompression via the colorectal tube. Pathological findings were: S, circ, type 2, 70×50mm, tub1>muc, pT3, pN0, H0, P0, M0, and pStage Ⅱ; no cancer cells were identified in the abdominal wall.
Colorectal cancer should be considered in patients with unknown abdominal wall abscesses. Furthermore, surgery should be taken into consideration after abscess drainage, to improve inflammation.
