[Undifferentiated small cell carcinoma of the urinary bladder. Clinicopathologic and immunohistochemical study].
Small cell carcinoma of the bladder ("oat cell") is a very uncommon tumor. Its sudden onset, rapid progression to an often fatal outcome and early metastatic spread are the main clinical features of this tumor. Immunohistochemical staining for neuroendocrine markers is positive in a large number of cases. A case of small cell carcinoma of the bladder is described. The clinical course of the patient, as well as the histopathological and immunohistochemical findings are presented.
