title: Fibroepithelial tumour of the renal pelvis.
abstract: From a statistical viewpoint, almost all renal pelvic tumours may be considered to be transitional cell carcinomas. Only six benign pelvic tumours have been reported in the English literature. The author describes one such case. A 40-year-old woman with recurrent cystitis was found on intravenous pyelography to have a mass in the right renal pelvis. Acting on the assumption that the mass was probably a transitional cell carcinoma, the author performed a nephroureterectomy. The fleshy intrapelvic mass turned out to be an extremely rare benign fibroepithelial tumour.
