Bladder paraganglioma — A report of two cases

摘要

Introduction Bladder paragangliomas (BP) are rare tumors, with clinical manifestations ranging from hypertension to hematuria to being asymptomatic. Histologically, they can mimic urothelial carcinomas. Around 200 cases of paragangliomas arising in the urinary bladder have been described in the world literature. Observation We report 2 new cases of BPs presenting with subtle clinical symptoms like increased urinary frequency. On routine cystoscopic examination of the bladder, bladder tumors were detected. Conclusion We would like to stress on the histomorphology and immunohistochemistry findings of this rare condition and its diagnosis on transurethral resection specimens.
