Dermatomyositis associated with adenocarcinoma of the lung: A case report.

The association of dermatomyositis and underlying malignancies, especially small cell and squamous cell carcinoma of the lung, has been recognized a long time ago. We report the case of a 63-year-old male chronic smoker with adenocarcinoma lung associated with dermatomyositis. The occurrence of dermatomyositis should be considered as a potential presentation of paraneoplastic syndromes and physicians encountering similar clinical situations should perform extensive diagnostic work-up to exclude underlying neoplastic lesions.
