Solitary Bladder Fibrous Tumor: A Case Report

The solitary fibrous tumor is an infrequent neoplasm of mesenchymal origin, mainly pleural, exceptionally urogenital. Our patient is 71 years old with no specific history who was presented to the emergency room for acute retention of urine relieved by a bladder catheter. An Uroscanner showed a thickening of the bladder wall which prompted the medical staff to perform a RTUV whose histological and immunohistochemical study confirmed the diagnosis of a solitary fibrous tumor of the bladder. Solitary fibrous tumors remain slow-growing neoplasms regardless of their site. The prognosis and aggressiveness are difficult to specify. Recurrences, locoregional extension and distant metastases can be seen in 10 to 20% of cases.
