Erythroderma is an unusual cutaneous finding associated with dermatomyositis. There are only five cases of erythrodermic dermatomyositis reported in the English literature. We treated a case of erythrodermic dermatomyositis associated with a Bormann type 1 gastric cancer. The patient had a generalized, erythematous scaly eruption consistent with erythroderma and Gottron's papules as well as a heliotrope rash; these are the hallmark skin manifestations of dermatomyositis.
