Generalised granuloma annulare successfully treated with pentoxifylline.

Generalised granuloma annulare (GA) is a chronic disease of unknown aetiology and is recalcitrant to many treatment regimes. Some investigators have suggested that an immune medicated vasculitis may be involved in the pathogenesis of GA. We describe a patient with a ten year history of generalised GA, who showed dramatic clearing of the majority of papules after four weeks of treatment with pentoxifylline. This drug has shown promising results in the treatment of many dermatologic disorders including necrobiosis lipoidica diabeticorum, leukocytoclastic vasculitis and Raynaud's phenomenon. Pentoxifylline is thought to reduce blood viscosity via effects on all major blood components, and its clinical effectiveness in generalised GA lends support to a model of immune-medicated vasculitis in the pathogenesis of this disorder. Thus, pentoxifylline offers a well-tolerated and effective alternative to the treatment options available for patients with granuloma annulare.
