Tracheobronchial lesions are rare extramuscular complications for idiopathic inflammatory myopathies including dermatomyositis. We herein report a 65-year-old woman with tracheal ulcer during the progression of dermatomyositis-associated interstitial lung disease. Treatment with corticosteroids combined with immunosuppressive agents resulted in improvement of the tracheal ulcer and pulmonary involvement. We believe that the tracheal ulceration might reflect the disease behaviour of dermatomyositis and dermatomyositis-associated interstitial pneumonia.

A 74-year-old man was referred to our hospital because of a tracheal stenosis circumscribed with soft tissue density and a left pulmonary nodule. Open biopsy of a right submandibular lymph node revealed diffuse large B-cell lymphoma, and the malignant cells were positive for Epstein-Barr virus gene products. Bronchofiberscopy revealed a tracheal necrotizing ulcer. After chemotherapy, the tracheal ulcer resolved. To our knowledge, this is the first report of a case of Epstein-Barr virus-positive diffuse large B-cell lymphoma of the elderly with a tracheal ulcer.
