We herein report the first case, to our knowledge, of tracheobronchial ulcer with anti-melanoma differentiation-associated gene 5 (anti-MDA 5) antibody-positive interstitial lung disease (ILD). A 53-year-old man complained of shoulder and wrist pain and was suspected of having polymyalgia rheumatica at another hospital. Thereafter, treatment with prednisolone was started. Although his arthralgia improved, he suffered from progressive dyspnea on exertion and an abnormal shadow was noted on chest X-ray, so he was transferred to our hospital. Chest computed tomography scan revealed ground-glass opacities and intralobular septal thickening. We diagnosed him as having clinically amyopathic dermatomyositis associated with ILD based on the specific skin findings and elevated anti-MDA 5 antibody titer. Fiberoptic bronchoscopy showed ulcerations of the trachea and bronchus. Treatment with dose increments of prednisolone combined with other immunosuppressive drugs resulted in improvement of his respiratory condition and tracheobronchial lesions. Clinicians should be aware that tracheobronchial ulcers can be associated with anti-MDA 5 antibody-positive interstitial lung disease.
