Neuroendocrine tumor of the bladder.

Small cell carcinoma (SCC) of the bladder is a rare and aggressive tumor associated with a poor prognosis. It often presents at a later stage than urothelial carcinoma of the bladder, and comprises less than 1% of bladder malignancies. A number of treatment algorithms have been used to treat bladder SCC, including cystectomy, partial cystectomy, radiotherapy, chemoradiotherapy, chemotherapy alone, and neoadjuvant/adjuvant chemotherapy. Presented is a case of SCC of the bladder, and the epidemiology, prognosis, and current treatment algorithms for patients with bladder SCC are reviewed.
