title: Solitary fibrous tumor in bladder wall.
abstract: The solitary fibrous tumor is a rare mesenchymal tumor, occurring preferentially in pleura, which has recently been described in extrathoracic sites. There are 6 reports on primary solitary fibrous tumor of bladder. They affect preferably men with mean age around 57 years, are usually asymptomatic and, despite eventually presenting morphologic features of malignancy, tumor resection is considered curative. We report the seventh case of solitary fibrous tumor in bladder wall, discussing differential diagnoses, and call the attention to this rarely occurring entity, which has benign behavior and should be managed conservatively.
