Abstract

Steroid myopathy is one of the most common drug-induced myopathy. We report a case of iatrogenic steroid myopathy in a 61-year-old female who had taken herb medication more than 2 months. She presented a slowly progressive proximal muscle weakness and wasting with typical features of cushing syndrome. Needle EMG showed typical myopathic patterns. The muscle biopsy revealed a pronounced muscle fiber atrophy and fatty degenerative change without inflammation. In addition, there was a selective type 2 fiber depletion on ATPase staining in pH 9.4 buffer. Her muscle powers and bulks were slowly improved after discontinuation of herb medication with phenytoin and physical therapy.
