A Case of Inverted Papilloma of Urinary Bladder / 대한비뇨기과학회지

ABSTRACT

Inverted papilloma of the urothelium is a rare, benign polypoid lesion which has typical histologic findings. Microscopically, a nonpapillary urothelium covers the surface from which cords of same epithelium invert and extend deep into the core in an anastomosing pattern, always maintaining its benign histological characteristic. Recently, we experienced a case of inverted papilloma of the bladder in 23-year-old male.
