title: Amyopathic dermatomyositis complicated by pneumomediastinum.
abstract: Dermatomyositis is an inflammatory disease of unclear etiology with characteristic cutaneous and musculoskeletal findings. Amyopathic dermatomyositis is a subtype without musculoskeletal involvement. Many cases of dermatomyositis are associated with underlying malignancy, but pulmonary manifestations can also be seen, the most common of which is interstitial lung disease. Pneumomediastinum is a rare complication that is important for clinicians to recognize, as it may be fatal if left untreated. The sudden onset of facial edema and shortness of breath in the setting of dermatomyositis should raise the suspicion of this condition.
