Seborrheic dermatitis-distributed dermatomyositis: a special type of dermatomyositis / 中华皮肤科杂志

ABSTRACT

Seborrheic dermatitis-distributed dermatomyositis, a special type of dermatomyositis, is characterized by facial seborrheic dermatitis-distributed rashes, usually accompanied by Gottron papules, inverse Gottron papules, mechanic′s hands and skin ulcers, seldom accompanied by muscle involvement. Anti-melanoma differentiation-associated gene 5 (MDA5) antibody-positive patients with seborrheic dermatitis-distributed dermatomyositis are prone to interstitial lung disease/rapidly progressive interstitial lung disease. Early diagnosis of seborrheic dermatitis-distributed dermatomyositis can be made through the combination of rashes and antibody detection, and early and active combined treatment with glucocorticoids and immunosuppressors can improve the survival rate of patients.
