[Inverted papilloma of the female urethra]

Abstract

Objective: Transitional cell inverted papilloma is an uncommon, generally benign tumor that rarely presents in the lower urinary tract. It is characterized by a typical inverted growth pattern and a layer of normal transitional epithelium. One such case is described herein.

Methods: We report on a 53-year-old female with transitional cell inverted papilloma of the urethra presenting as postmenopausal metrorrhagia. The lesion was removed surgically.

Results: It was a round-shaped, 1.5 cm diameter, polypoid lesion that was resected. Standard pathological analyses disclosed a trabecular type inverted papilloma.

Conclusions: Transitional cell inverted papilloma of the female urethra is rare. To date it has only been reported in male patients. An additional case of this tumor type is described in a female patient.
