Abstract

We encountered a patient with dermatomyositis complicated by sarcoidosis. A 57-year-old woman was admitted to our hospital because of fever, dry cough, and myalgias. There were reticular shadows on her chest X-ray film. Although the typical skin rash and myostitis suggested the diagnosis of dermatomyositis, biopsy specimens from a salivary gland, muscle, and lung revealed noncaseating granulomas as well. Uveitis was also noted. These findings suggested the coexistence of sarcoidosis with dermatomyositis. Examination of the lung-biopsy specimens showed interstitial pneumonia compatible with dermatomyositis, except for the granuloma. The typical rash of dermatomyositis and pathological findings of the lung specimen were inconsistent with sarcoidosis. Therefore we concluded that this patient had both dermatomyositis and sarcoidosis. This case sheds new light on the importance of pathological examinations.
