Gastrointestinal angiodysplasia in three Saudi children.

Angiodysplasia is a term used to describe distinct gastrointestinal mucosal ectasias that are not associated with cutaneous lesions, systemic vascular disease or a familial syndrome. Seventy-seven percent of angiodysplasia are located in the cecum and/or ascending colon. Fifteen percent are located in the jejunum and/or ileum and the remainder are distributed throughout the alimentary tract. Most commonly, the angiodysplastic lesions are typically seen in elderly patients of both genders, although gastric and duodenal lesions have been reported occasionally in subjects within the third decade of life. However, data on infants and children are scarce. We describe three cases (ages 7 days, 2 years, and 5 years) who presented to our unit with gastrointestinal bleeding. One of these patients developed moderate-to-severe symptoms and was blood-transfusion dependent. She was misdiagnosed as having inflammatory bowel disease and underwent a total colectomy and ileoanal anastomosis. The other two patients were managed conservatively for up to 5 years with no further bleeding.
