Abstract

We report the case of a 32-year-old female who developed polymyositis associated with scrub typhus. She exhibited the eschar with high titer of anti-Rickettsia(R)-tsutsugamushi antibody, severe muscle weakness, markedly elevated serum levels of muscle enzymes, EMG changes, and infiltration of macrophages in a muscle biopsy specimen. Initiation of appropriate antibiotic therapy resulted in complete healing of scrub typhus and disappearance of symptoms and signs of polymyositis within 1 month after high dose steroid therapy. We suggest that scrub typhus also be included within the causes of idiopathic inflammatory polymyositis.
