Rare cause of recurrent iron deficiency anemia

摘要

Blue rubber bleb nevus syndrome (BRBNS) is a rare disorder, characterized by multifocal venous malformations predominantly affecting skin, soft tissues, and gastrointestinal (GI) tract. Its presentation is usually sporadic although cases of autosomal dominant inheritance have been reported. Usually seen in children, BRBNS presentation in adults is rare. Most common symptoms of GI tract involvement are iron deficiency anemia and bleeding. We present a case of 16-year-old boy, who presented with recurrent anemia requiring multiple blood transfusions.
