Blue rubber bleb nevus syndrome

Blue rubber bleb nevus syndrome is a rare disorder characterized by distinc tive cutaneous and gastrointestinal venous malformations that usually cause massive or occult gastrointestinal hemorrhage and iron deficiency anemia s econdary to the bleeding episodes. It is even a rare cause of gastrointesti nal hemorrhage during childhood. We describe a 6-year-old boy who had multi ple venous malformations all over his body. He also suffered from several e pisodes of melena, chronic anemia, and growth retardation. The endoscopic e xamination of the gastrointestinal tract revealed multiple bluish-black ses sile and polypoid venous malformations in various sizes. It was possible to remove the largest venous malformations causing massive bleeding during co lonoscopy.
