[Asymptomatic bladder paraganglioma. Report of a case].

Paragangliomas are tumors which arise from collections of neuroepithelial cells (paraganglion system) scattered throughout the body and rarely in the urinary bladder. In this work, we described a case of bladder paraganglioma, not suspected in a 64-year-old male who showed occasional total hematuria as only symptom. Cystoscopically, it was diagnosed as a rounded, not papillary tumor, one centimeter in diameter on account of which it was subjected to TUR. Confirmed the diagnosis, a partial cystectomy and a limited regional lymphadenectomy were subsequently practised. Posterior evolution, after a year, was completely favourable. The main clinicopathologic characteristics of this entity are revised.
