Angiodysplasia or arteriovenous malformation of the gastrointestinal
tract in younger patients is different from "classic" angiodysplasia in older patients,
by age of onset, clinical presentation, location of the lesion and diverse histologic
features, We report two cases of juvenile angiodysplasia of the gut. The diagnosis
was suspected by radionuclide blood pool scan and was confirmed by resection and
pathological examination, Both cases were girls of 5 years and 12 years of age, and
the lesions were in the jejunum and ileum, Grossly, one case showed multiple
petechiae and another case showed a hemorrhagic polypoid mass, Microscopically,
the lesions were composed of irregularly dilated vascular channels in mucosa and
submucosa with abnormal proliferation of arteries and veins in submucosa, Both
cases are free of recurrence after local resection
