title: Unilateral limited scleroderma-like changes following formation of an arteriovenous fistula.
abstract: A 55-year-old man presented with a 1-year history of progressive skin thickening involving the right hand associated with Raynaud's phenomenon, sclerodactyly and painful cutaneous ulcers. An arteriovenous fistula for haemodialysis had been formed on the same arm 2 years previously. There were no symptoms or signs of systemic sclerosis or involvement of the contralateral arm. The limb was clinically ischaemic, attributed to a vascular steal phenomenon from the arteriovenous fistula, superimposed on occlusive arterial disease. A revascularization procedure was performed, which resulted in substantial improvement in the sclerodactyly, Raynaud's phenomenon and hand function. Tissue hypoxia is believed to be a contributing factor in the pathogenesis of scleroderma, and this case demonstrates scleroderma-like changes in the setting of limb ischaemia.
