Blue Rubber Bleb Nevus Syndrome in the Colon, Tongue, and Supraglottic Region: Case Report

Abstract

Blue Rubber Bleb Nevus Syndrome (BRBNS) is an extremely rare and likely hereditary condition characterized by the presence of numerous hemangiomatous lesions that are purplish, raised, and elastic, primarily affecting the skin and the digestive system. These lesions become prominent and rubbery to the touch. BRBNS can also affect other organs. Clinically, it may be asymptomatic or present with painful skin lesions, hyperhidrosis, abdominal pain, gastrointestinal bleeding, anemia, and hematuria, among other signs and symptoms. Treatment options include conservative management, pharmacological intervention, endoscopic procedures, or surgery. This report presents the clinical case of a 22-year-old woman with a history of BRBNS affecting the skin and lips but with no gastrointestinal symptoms. She is under dermatological follow-up and management. The patient was seen on an outpatient basis at the endoscopy unit of Unión de Cirujanos S.A.S. in Manizales, Colombia, at the Clinical-Surgical Gastroenterology Service of the Universidad de Caldas. An upper digestive endoscopy (EVDA) and ileocolonoscopy were performed to rule out the presence of similar lesions in the gastrointestinal tract. The EVDA revealed vascular, raised, rubbery lesions at the base of the tongue and in the supraglottic region, with no involvement of the esophagus, stomach, or duodenum. The ileocolonoscopy showed multiple vascular, raised lesions in the cecum, transverse colon, and descending colon.
