Gastrointestinal (GI) angiodysplasia is a vascular lesion. It is a common cause of GI bleeding in chronic renal failure (CRF). We report three adult chronic hemodialysis patients with asymptomatic angiodysplasia. Over a period of four years, the hemoglobin level was stable and none of our patients received iron supplementation or erythropoietin (EPO) therapy. Incidence of angiodysplasia may be underestimated in the CRF patients. Further studies may be needed.
