Diffuse dermal angiomatosis due to an iatrogenic arteriovenous fistula.

Sir, Reactive angio-endotheliomatosis (RAE) is a rare skin condition characterized by a diffuse proliferation of endothelial cells within the vascular lumina with secondary intravascular thrombi, resulting in obliteration of involved blood vessels. Clinical features are variable with both generalized and localized forms recognized (1, 2). We describe here a patient with Wegener’s granulomatosis (WG), who developed a localized patch of diffuse dermal angiomatosis, a subtype of RAE, distal to an arteriovenous fistula required for haemodialysis.
