Paragangliomas involving the urinary bladder are rare neoplasms which probably account
for less than 0.5% of all bladder tumors. The first instance of a paraganglioma of the
urinary bladder was reported by Zimmerman et al., in 1953. Since that report, about 40
additional case have appeared in the world literatures and in the domestic area, it was
not described nowadays. Recently, the authors experienced a case of paraganglioma
arising from the urinary bladder in a 44 years old female, who complained frequency,
microhematuria and pain on urination.
The reported case illustrated certain histologic variation, histogenetic concepts and
clinical features of paraganglioma involving the urinary bladder
