Pheochromocytomas and paragangliomas (extra-adrenal pheochromocytomas) are catecholamine-secreting tumors. The paraganglioma of the urinary bladder is an uncommon neoplasm with a higher malignancy rate. Only about 60% of bladder paragangliomas presented with hematuria, and most of them were microscopic hematuria. Herein, we report two cases of bladder paraganglioma with bladder bloody tamponade. In Case 1, radical cystectomy and regional lymphadenectomy were performed for a huge bladder tumor and left pelvic lymph nodes metastasized. In Case 2, we chose endoscopic transurethral resection of the bladder tumor. Literatures since 1989 were also reviewed to illustrate the clinical characteristics and current treatments.

Rhabdomyosarcoma (RMS) is the most common soft tissue tumor of childhood; about 80% of cases occur before the age of 21 with the remaining 20% evenly spread throughout the remaining decades. A primary paratesticular site is considered to have a good prognosis in comparison with other RMS sites. Histologically, any subtype of RMS, including alveolar, pleomorphic, embryonal, and mixed type, may occur in the paratesticular region, but only a relatively small number of cases are mixed and this variant has a poor prognosis. We report a case of paratesticular RMS (mixed embryonal and alveolar type) in a 16-year-old boy.
