Abstract:
Primary undifferentiated small cell carcinoma of the urinary bladder is a rare tumor. This tumor is basically identical to that of the small cell carcinoma of the lung in clinicopathologic aspect. The origin of the tumor is still obscure, but two hypothesis are proposed. The first is normal and metaplastic neuroendocrine cells located in the bladder mucosa. The second is proliferating mucosal stem cells with multidirectional differentiation. We report a case of undifferentiated small cell carcinoma of the urinary bladder in a 65 year-old man, who presented symptom of hematuria.
