Abstract
Pseudosarcomatous fibromyxoid tumors are benign tumors of the urinary bladder with clinical presentation similar to that of malignant lesions. This is a case of a 43 year-old male presenting with painless gross hematuria. Personal history and CT urogram are suggestive of a malignant bladder tumor. On cystoscopy, a 1cm x 2.5cm pedunculated polypoid mass was appreciated at the lower lip of the right ureteral orifice. Transurethral resection of the bladder tumor was subsequently done. Ureteroscopy of the right distal ureter was also done revealing no gross involvement of the tumor. Histopathologic examination of the mass revealed pseudosarcomatous fibromyxoid tumor. Review of current literature highlights the rarity of this disease entity, the relative technical difficulty of distinguishing it from malignant lesions, and its benign clinical course excluding the need for more aggressive treatment regimens.
