Inverted papilloma, a Crying wolf of the urinary bladder

Abstract

Inverted papilloma is a benign, non-invasive and innoxious bladder tumour rarely seen. These tumours are associated with chronic urinary tract infection, bladder neck obstruction, and they appear similar to other bladder tumours. Inverted papilloma is diagnosed on histopathological examination. We report a case of inverted papilloma who presented and appeared as bladder tumour but on subsequent pathological examination diagnosed as inverted papilloma.
