A Case of Sigmoid Colon Cancer with a Pulmonary and a Liver Abscess

Abstract

A 57-year-old man presented with lower abdominal pain and fever. A thoracoabdominal computed tomography revealed a pulmonary abscess (S8), a liver abscess (S4) and wall thickening of the sigmoid colon. Colonoscopy revealed a type 2 tumor in the sigmoid colon. He was diagnosed as having sigmoid colon cancer, cT3N0M0 Stage IIa with the pulmonary abscess and the liver abscess. A puncture drainage of the liver abscess yielded α-streptococcus. His general condition was recovered by administration of an antibacterial agent and the percutaneous trans-hepatic abscess drainage (PTAD). Subsequently, we performed sigmoidectomy with D3 lymphadenectomy. The histopathological diagnosis was tub1, pT3N0M0 Stage IIa. He has been free from any recurrence of colon cancer and abscesses, as of 2 years after the operation.
