title: [Gastric cancer associated with dermatomyositis accompanied by photoallergy].
abstract: A 62-year-old man was admitted to the hospital because of a 5-month history of edematous erythema and itching on the face, upper chest, and upper extremities. The symptoms developed immediately after bathing in the sea. Dermatomyositis associated with photoallergy was diagnosed by skin and muscle biopsy. A search for malignancy revealed Borrmann 3 gastric cancer, and subtotal gastrectomy was performed. He has done well for 3 years and 8 months after the operation, but there has been no remission in the symptoms of dermatomyositis. Dermatomyositis associated with photoallergy has a higher incidence of complications with malignant disease than ordinary dermatomyositis.
