title: Urticarial vasculitis and dermatomyositis in a patient with nasopharyngeal carcinoma.
abstract: Urticarial vasculitis has rarely been described in association with polymyositis. We report the case of a 37-year-old man with dermatomyositis and nasopharyngeal carcinoma who presented initially with urticarial vasculitis. The lesions of urticarial vasculitis were initially photodistributed, indicating photosensitivity. The patient was treated with systemic steroids, chemotherapy (cisplatin and fluorouracil), and radiation therapy. The tumor and urticarial vasculitis completely resolved, and the myositis improved.
