The present study describes a case of pseudosarcomatous lesion of the urinary bladder, a rare disease entity that may occasionally be clinically mistaken for malignant neoplasms.
METHODS/RESULTS: A 79-year-old male with hematuria who had previously undergone surgery is described. Cystoscopic examination revealed a tumor which was resected by TUR. The histological analysis disclosed a benign proliferative mesenchymal lesion comprised of spindle cells.
Pseudosarcomatous lesions of the urinary bladder are benign lesions of fibroblastic or myofibroblastic origin that are more frequent in young adults and prevalent in females. Clinically they present with hematuria and treatment is by surgical excision (partial cystectomy or TUR). The prognosis is excellent.
