Association between the synthetic vascular stent used for abdominal aortic aneurysm and generalized granuloma annulare

Abstract

Abstract The etiology of granuloma annulare (GA) remains unknown, although several eliciting factors have been proposed. We herein present the case of an 81-year-old man who developed generalized erythematous annular plaques 6 months after engraftment of a vascular stent for abdominal aneurysm repair. Based on the diagnosis of generalized GA and the patient's age, we treated him with psoralens plus ultraviolet A therapy. The treatment response was good. This is the first report showing the association between vascular stent and generalized GA.
