Amyopathic dermatomyositis is diagnosed when the biopsy-confirmed cutaneous lesions of dermatomyositis are present for longer than 2 years in the absence of muscle weakness, elevated muscle enzymes, and the history of immunosuppressive drug therapy and ingestion of drugs such as hydroxyurea that can produce dermatomyositis-like cutaneous hypersensitivity changes. We report a 36-year-old woman with a 3-year history of typical skin features of dermatomyositis with no evidence of muscle involvement. (Korean J Dermatol 2001;39(7): 827-828)
