A rare Para neoplastic manifestation associated with squamous cell carcinoma of bladder: dermatomyositis

Abstract

Dermatomyositis is a rare Para neoplastic syndrome, especially in urinary tract malignancy. We report a case of bladder squamous cell carcinoma in a 50-year old patient who presented with Para neoplastic dermatomyositis when tumor recurred. A radical cystectomy was performed for him and symptoms of dermatomyositis improved dramatically. The case shows that complete resection of bladder cancer may lead to resolution of Para neoplastic dermatomyositis and to our knowledge it is the first case of dermatomyositis in association with squamous cell carcinoma of bladder reported.
