A Case of a 14-Year-Old Girl Who Developed Dermatomyositis Associated with Mycoplasma pneumoniae Infection

Abstract

Extrapulmonary manifestations of Mycoplasma pneumoniae infection are not uncommon and involvement of every organ system has been reported. However, association of inflammatory myositis with M. pneumoniae infection is rare. Here, we describe a patient who developed polymyositis associated with mycoplasma infection, who was treated successfully with glucocorticoid, intravenous immunoglobulin, and methotrexate.
