Case 1. A 48-year-old man with no history of hypertension was referred to our hospital with a 1 cm bladder tumor. According to cystoscopy, magnetic resonance imaging and I-MIBG scintigraphy, we diagnosed it as a paraganglioma of the bladder. Partial cystectomy was performed. The histological findings supported the diagnosis of paraganglioma of the bladder. Six years later, he was free of any evidence of recurrence. Case 2. A 64-year-old woman with hypertension was pointed out to have a 1cm bladder mass by ultrasound in a health examination. She was referred to our hospital for further examination. Cystoscopoy revealed a 1 cm intramural nodule covered by intact urothelium at the right posterior wall. Submucosal bladder tumor was not diagnosed as paraganglioma by cold punch biopsy. So, transurethral resection of the bladder tumor was performed for differential diagnosis. The tumor was hypervascular and involved the muscular layer of the bladder. Although a transient elevation of blood pressure occurred during the procedure, the tumor was resected as completely as possible. The histological diagnosis was paraganglioma of the bladder. She has been followed up for 27 months after operation without any evidence of recurrence.
