A 70-year-old man with pruritic erythema on his back was reported. The erythema had been present for 4 months and expanded to both knees and dorsal surface of both hands. Muscle weakness of the lower limbs was also recognized. Based on various clinical and histopathologic examinations, the patient was diagnosed as having dermatomyositis. Peripheral blood examination revealed pancytopenia and atypical lymphocytes. Additional bone marrow aspiration confirmed the diagnosis of acute myelogenous leukemia. It is well known that dermatomyositis tends to accompany internal malignancies. However, only 3 cases of dermatomyositis accompanied by acute myelogenous leukemia have been reported worldwide.
