[Angiodysplasia of the colon. Apropos of a case]

A case of angiodysplasia of the right colon is reported. Clinical, radiological, endoscopic and pathological aspects are described. Beside the arteriography, the authors insist on the special usefulness of the coloscopy which helps the diagnosis and gives therapeutic possibilities as well by electrocoagulation of the lesion. Vascular opacification of the specimen is very useful to help the pathologist.
