Klippel–Trénaunay–Weber Syndrome - A Rare Case Report

Abstract

Klippel–Trenaunay–Weber syndrome (KTWS) is a rare congenital vascular disorder characterized by capillary malformations, venous abnormalities, and soft-tissue or skeletal hypertrophy; a 25-year-old male presented with pain in the upper right posterior teeth for 6 months. Examination revealed a right-sided Port–Wine stain, unilateral left limb hypertrophy, and bilateral blue sclera. Medical history revealed gastric antral ulcers on endoscopy, mitral valve prolapses on echocardiography, and ectatic retinal vessels with increased retinal thickness on optical coherence tomography. Based on the medical history and clinical findings, diagnosis of KTWS was established. The patient was managed conservatively with multidisciplinary follow-up. This case highlights the diverse manifestations of KTWS and underscores the role of dental professionals in early recognition and long-term surveillance for optimizing outcomes.
