Resident rounds. Part III. A case of dermatomyositis presenting with eyelid nodules

摘要

Dermatomyositis (DM) is a type of idiopathic inflammatory myopathy. DM can be classified into adult and childhood types. Adult DM can be further subdivided into classic DM, amyopathic DM, and DM with overlap.1 Patients with classic DM typically have a symmetric proximal muscle weakness and characteristic skin findings of macular violaceous erythema and Gottron's papules.1 The macular violaceous erythema can be located periorbitally (heliotrope sign), overlying the dorsal finger joints (Gottron's sign), chest (V-sign), lateral thighs (holster sign) or back/shoulders (shawl sign). Other skin findings include mechanics hands, flagellate erythema, periungal abnormalities, cal-cinosis cutis, seborrheic dermatitis-like rash and erythroderma.
