Visceral involvement affects mostly the gastrointestinal (GI) system. As these venous malformations can lead to life-threatening serious GI bleeding, anemia is an important clue to diagnosis. A 18-year-old female presented to the department of internal medicine with complaints of weakness and paleness. Hypochromic microcytic anemia was diagnosed and upper and lower GI screenings were done. On endoscopy, reddish-purple polypoid lesions were detected throughout the GI tract and nodular lesions compatible with venous malformations were observed on both lower extremities. A diagnosis of BRBNS was made. Symptoms of iron deficiency anemia guide patients with BRBNS to general practitioners and internal medicine specialists. If cutaneous findings are present, collaboration with dermatologists at this stage will improve diagnostic accuracy.eninfo:eu-repo/semantics/closedAccessAnemiaCutaneous HemangiomaGastrointestinal TractArticle293411413WOS:0003379272000122-s2.0-84885984182N/AQ4
