ABSTRACT
Background: Klippel-Trenaunay syndrome (KTS) is a rare congenital disease that mainly involves blood vessels and is characterized by the presence of capillary malformations (port wine stains), varicose veins, soft tissue and/or bone hypertrophy. Case Presentation: We report a 28-year-old man who was diagnosed 20 years ago with Klippel-Trenaunay syndrome. Approximately 3 years ago, he found enlarged masses on both upper extremities and a new dark red mass that was pathologically diagnosed as cavernous haemangioma appeared on the right index finger. Conclusion: KTS is a rare and potentially multisystem disease requiring multidisciplinary management for which imaging examination is an important auxiliary diagnostic method. Various complications may occur during its development, so regular follow-up is required to prevent serious accidents.
