Aseptic olecranon bursitis as a novel subcutaneous manifestation of dermatomyositis.

摘要

A 32-year-old woman developed reddish macules on both eyelids and pruriginous edematous erythematous lesions on the shoulders and thighs. The patient also showed erythematous cutaneous lesions on the bilateral elbows and knees, bilateral extensor sites of the upper aspects of the arms, and the periungual nailfolds. Four months later, she presented with proximal muscular pain and weakness that became gradually worse. On referral to our clinic, physical examination revealed fluctuating cystic soft tissue swelling with superficial scaling erythema on the bilateral elbows (figure 1C) in addition to the typical observations of heliotrope periorbital edema (figure 1A), Gottron's papules (figure 1B).
