title: Inverted papilloma of urinary tract.
abstract: The inverted papilloma of the urinary tract is a rare tumor; few urologists and pathologists are aware of its existence. Even if the histogenesis of the lesion is unknown, the correct diagnosis is essential, since its behavior appears totally benign, contrary to transitional cell carcinoma. We report 3 new cases, one originating in the renal pelvis, and one in an eighteen-year-old woman.
