title: Primary small cell carcinoma of the urinary bladder. Report of a case with immunohistochemical analyses.
abstract: A case of primary small cell carcinoma of the urinary bladder is reported. The light-microscopic diagnosis was supported by immunoreactivity for HISL-19 (marker for peptide-hormone-producing cells) and for neuron-specific enolase (NSE), demonstrating the neuroendocrine differentiation of this rare bladder tumor. Serum NSE, which was significantly elevated, can be a marker for disease extent and response to therapy.
