Dermatomyositis in association with transitional cell carcinoma of the bladder.

There is a well-recognized association between the inflammatory dermatomyopathy, dermatomyositis, and underlying visceral malignancy in adults. It is most commonly found in association with malignancies arising in the lung, breast and stomach. We report a case found in association with transitional cell carcinoma of the bladder, a site where there have only been a handful of previous reports.
