ABSTRACT
A 77-year-old woman presented with rash, muscle pain, muscle weakness, and dysphagia after the third dose of COVID-19 vaccine. Chest computed tomography showed a mass shadow in the right lower lobe. Finally, she was diagnosed with extensive-stage small-cell lung cancer and anti-transcriptional intermediary factor (TIF)1-γ antibody-positive dermatomyositis. Chemotherapy and systemic corticosteroids improved the symptoms of dermatomyositis and produced a partial response to lung cancer. We should consider dermatomyositis when rash or muscle symptoms appear after COVID-19 vaccination.
