Drug-induced amyopathic dermatomyositis.

Amyopathic dermatomyositis is a rare condition. We describe the clinical and histopathologic findings of a 53-year-old woman who developed cutaneous lesions similar to those described in dermatomyositis after fibrate therapy for hypertriglyceridemia. Our patient fits the proposed criteria for amyopathic dermatomyositis, and after 8.5 years, muscular involvement has not been detected, although the dermatologic lesions are still present despite different treatments reported to treat this condition (steroids, antimalarials, methotrexate, dapsone). However, an initial good response has been observed with thalidomide, a drug used increasingly in the dermatologic field. As far as we know, this case is the first of drug-induced amyopathic dermatomyositis.
