A 63-year-old male patient presented with recurrent attacks of painless gross hematuria 1 year back with no history of hypertension. Physical examination was unremarkable except overweight (135kgm). Urine analysis revealed red blood cells with negative urine culture for any bacterial growth. Urine cytology for malignant cells was also negative. Computed tomography scan of abdomen and pelvis showed a well-defined solid mass 1.4cm located in the anterior wall of the urinary bladder. Cystoscopy revealed a protruding red to- pink bladder mass with normal smooth mucosa with the intraoperative provisional diagnosis of an urothelial bladder tumour. The patient underwent to trans-urethral resection of bladder tumour (TURBT) for the most visible lesion with no single episode of intraoperative hypertension through anaesthesia record sheet. The histopathology of the resected mass and Immunohistochemistry has confirmed the diagnosis of paraganglioma of the urinary bladder. Three Months post-operative follow-up revealed no evidence of recurrent bladder tumour.
We report a case of nonfunctional paraganglioma of the urinary bladder of an unusual location with no suspicion before final diagnosis.
