Summary

A 38-year-old woman was referred to a dermatologist because of a rash in the face. She had been feeling low in energy for several months and in the past two months her arms and legs felt weak accompanied by myalgia. The rash had expanded to the extensor surfaces of hands and knees, upper chest, and neck. Serum CK was 4313 U/L (20 × ULN), and she was referred to the outpatient department for neuromuscular disorders with a presumed diagnosis of dermatomyositis.
