title: An unusual colonic lesion associated with chronic gastrointestinal bleeding.
abstract: A 71-year-old woman suffering from mild anemia with an hemoglobin level of 10.7 g/dL (normal ≥ 12 g/dL) was referred to our unit for further endoscopic evaluation. Upper gastrointestinal endoscopy revealed no abnormal findings. Colonoscopy detected a smoothly lined, thin and worm-like polyp measuring 6 cm in length with minor erosions on its surface. It was located in the left transverse colon. Microscopic examination of the resected specimen disclosed the very rare case of a colonic polypoid cavernous hemangioma. Recurrent latent bleeding from this lesion could be responsible for the observed mild anemia in this patient. A review of the literature and suggestions for endoscopic treatment are given.
