Note 1: Typical skin changes include a heliotrope rash, and red or violet, sometimes scaly, slightly raised papules that erupt on the finger joints or other bony extremities (Gottron papules). Typical muscle disease involves progressive and symmetrical weakness of the limb-girdle muscles, with or without dysphagia and respiratory muscle weakness. Note 2: The diagnosis may be confirmed by elevation of serum levels of muscle-associated enzymes, biopsy, imaging or the presence of myositis-associated antibodies.
