[Inflammatory bladder pseudotumor]

The inflammatory pseudotumor of the urinary bladder or pseudosarcomatous fibromyxoid tumor is a benign proliferative mesenchymal spindle cell process, usually polypoid. This rare benign lesion in the majority of the cases have been observed in children and young adults, with only a few cases reported in patients older than 50 years; there are approximately 75 cases in the literature. We present a case of inflammatory pseudotumor verified histologically and treated by tumoral resection and left ureteral reimplantation with antireflux technique. This patient presented initially macroscopic hematuria and required transfusions of packed red cells and frozen fresh plasma. This shows the importance of the diagnosis to establish the definitive treatment as early as possible.
