Dermatomyositis. Moderate erythematous rash is appreciated along the hairline of the scalp, the malar region of the face, and the eyelids—later the heliotrope rash (A). Macular erythematous rash is seen over the extensor surface of the knuckles (Gottron’s sign) (B). Gottron’s papules are the papular lesions seen here on the knuckles (C). Dilated capillary loops are evident in the nail bed changes as well as a small ulceration involving the distal aspect of the little finger (D).
