Cutaneous ulcers associated with vasculitis are rarely reported in adult-onset dermatomyositis (DM), and are often resistant to treatment, resulting in a poor prognosis. There is no general treatment strategy and the effects of various treatments have never been confirmed histopathologically. A 43-year old man with DM developed refractory multiple cutaneous ulcers which were revealed as vasculitis by skin biopsy. Repeated intravenous cyclophosphamide pulse therapy (IV-CY) without high-dose corticosteroid therapy resulted in complete resolution of the ulcers without adverse effects or severe complications. A repeat biopsy confirmed complete remission of vasculitis. Repeated IV-CY is a useful treatment for induction of clinical remission of DM with cutaneous vasculitis.
