title: Recurrent episodes of dermatomyositis-associated pneumonitis masquerading as hypersensitivity pneumonitis.
abstract: This case report describes a unique presentation of dermatomyositis-associated pneumonitis. A 44-year-old man presented with repeated episodes of fever, dyspnea, and hemoptysis accompanied with pulmonary infiltrates, on chest CT scan. Hypersensitivity pneumonitis was suspected. Further work-up showed clinical and serologic evidence of dermatomyositis-associated pneumonitis. The patient was treated with oral prednisone and azathioprine. The subject of dermatomyositis-associated pneumonitis is discussed.
