Pseudo‐Kaposi sarcoma induced by minor trauma in a patient with Klippel–Trenaunay–Weber syndrome

Arteriovenous malformations (AVM) are vascular anomalies containing a communication between an artery and a vein without an intervening capillary bed. 1 In 1990, Klippel and Trenaunay reported a patient ith limb overgrowth, cunateous angiomata and varicose veins. 2 In 1918, Parkes Weber mentioned the additional feature of AVM terming the condition «hemangiectatic hypertrophy». 3 Most authors now consider both Klippel-Trenaunay syndrome and the syndrome of multiple congenital arteriovenous fistulae to be two forms of Parkes Weber's hemangiectatic hypertrophy. 4
