[Fever and leukemoid reaction in bladder cancer: report of a case]

The authors present a unique case of bladder cancer that presented as paraneoplastic syndrome of fever and leukemoid reaction. Furthermore, the patient had a left renal tumor histologically similar to the bladder tumor. We discuss whether the foregoing was a metastatic or a primary tumor coexisting with a bladder tumor. The neoplastic syndromes affecting patients with bladder neoplasms are briefly discussed.
