Characteristic nail fold changes were a consistent finding in a series of six patients with dermatomyositis. They showed remission and recurrence paralleling the severity of the dermatomyositis and serum enzyme measurements. Capillaroscopic studies on the affected cuticles in two additional patients showed findings characteristic of dermatomyositis.
