A Case of Prostate Cancer Associated with Dermatomyositis and Interstitial Lung Disease / 대한내과학회지

ABSTRACT

Dermatomyositis (DM) is a kind of systemic autoimmune disease characterized by chronic inflammation leading to progressive weakness of proximal muscles and typical cutaneous lesions. DM has been known to be strongly associated with malignancies, such as ovarian, lung, and gastric cancers. Prostate cancer is rarely associated with DM and, to our knowledge, no case of prostate cancer has been reported in patients with DM combined with interstitial lung disease in Korea. Here, we report a case of DM with bronchiolitis obliterans organizing pneumonia that was simultaneously diagnosed as advanced prostate cancer by a thorough evaluation for hidden malignancy.
