Neutrophilic myositis (NM) is an inflammatory disorder predominantly characterized by neutrophilic infiltration in the muscles, which is suggested to be an extracutaneous manifestation of neutrophilic dermatosis (ND). NM is a rare disorder which has been occasionally reported in association with hematologic and inflammatory disorders. This case report describes a 45-year-old woman who presented with gradual muscle weakness developed after coronavirus disease 2019 (COVID-19) infection. Electromyography and nerve conduction velocity findings were compatible with inflammatory myopathy and muscle biopsy revealed neutrophilic infiltration. She was successfully treated with intravenous immunoglobulin, prednisolone 1 mg/kg/day and azathioprine 150 mg/day. In conclusion, the COVID-19 infection itself and the drugs used to treat it can cause a number of muscle disorders. Awareness of muscular involvement in COVID-19 infected patients is important for early diagnosis and appropriate treatment.
