Angiodysplasia Arising in the Bowels: Two cases report

  • 1Department of Anatomical Pathology, Inha Hospital, Sungnam 461-194, Korea.


Gastrointestinal angiodysplasia is a distinct disease entity which causes frequent gastrointestinal bleeding. It predominantly arises at the stomach and duodenum in the upper gastrointestinal tract and cecum and ascending colon in the lower gastrointestinal tract. The general histological finding of the angiodysplasia is a submucosal vascular ectasia and tortuosity. We have experienced two cases of the intestinal angiodysplasia. The first case occurred on a jejunum in a 22-year-old woman who had anemia. The second case occurred on a sigmoid colon in a 59-year-old man who had constipation. In addition to the general histologic finding of the angiodysplasia, the microscopic findings of the first case revealed some capillary hemangioma-like areas; and in the second case, there was a marked ischemic change and the thickening of the wall.
