Abstract:
Inverted papilloma is a rare urothelial neoplasm most frequently occurred in the trigonal region of the urinary bladder. But, it rarely arises in the renal pelvis. The characteristic downward proliferation of urothelial cells within the underlying lamina propria is of such magnitude as to result in an exophytic papillomatous tumor. It was regarded as a benign neoplasm, but the malignant tendency is now being reported with inverted papillomas of urinary tract, and therefore they are no longer regarded as innocuous benign neoplasms. We report a very rare case of inverted papilloma of the renal pelvis and review the relevant literatures.
