Excerpt

Inverted urothelial papilloma is a rare tumor that presents as a non-invasive endophytic urothelial neoplasm of the renal pelvis, ureter, or urinary bladder accounting for less than 1% of all urothelial neoplasms. Since its initial description by Paschkis in 1927, there have been more than 1,000 cases reported in the literature. It is usually detected incidentally during the cystoscopic evaluation of other conditions e.g. benign prostatic hyperplasia, hematuria or prostate cancer. It may present as gross or microscopic painless hematuria. However, the clinical and endoscopic features of inverted urothelial papilloma of the bladder are not specific, and the definitive diagnosis is based on the histopathological examination.
