A 16-year-old adolescent boy was admitted to our hospital with severe lower abdominal pain and was found to have peritonitis, probably caused by acute appendicitis. At laparotomy, we found a paper-thin, dilated sigmoid colon; the seromuscular layer on the antimesenteric side was torn, and the untorn mucosa showed a pinpoint perforation. The seromuscular defect had spread circumferentially to involve the entire circumference of the colon wall. We performed sigmoidectomy, and the patient recovered uneventfully. This case showed many similarities, both in terms of the macroscopic and pathologic findings, to seromuscular tear, an entity specifically associated with seatbelt use. This case is noteworthy because seromuscular tear-like lesions of the colon without a history of trauma has not previously been reported. [ABSTRACT FROM AUTHOR]
