Abstract

Angiolipoma is a benign tumor that is mainly observed in the subcutaneous tissue and is composed of mature adipose tissue and proliferative blood vessels. However, the condition is rare in the gastrointestinal tract including the colon. There was a case report of angiolipoma of the proximal ileum but there are no reports of angiolipoma of the colon in Korea. A 47-year-old man, who presented with intermittent left lower quadrant pain and hematochezia, underwent contrast enhancement CT, which revealed a huge mass with inhomogeneous density in the distal descending colon. The colonoscopy viewed a large polypoid mass with vascular engorgement, and a laparotomy was performed urgently due to the persistent abdominal pain, intussusception and hematochezia. The histology examination disclosed a benign angiolipoma. We report this case of symptomatic angiolipoma of the distal descending colon.
