title: Intraurethral condylomata acuminata associated with genital piercings.
abstract: A 33-year-old man was referred to our institution with papillary masses at the urethral meatus and difficulty urinating. Genital examination showed two piercings on the frenulum, which were penetrating the external urethra. Endoscopic examination revealed papillary tumours over the entire circumference of the penile urethra and the piercing site. The tumours were resected transurethrally. Microscopic examination revealed condylomata acuminata. Human papillomavirus types 6 and 66 were detected in the lesions. Retrograde urethral viral infection is rare because of the protection provided by the mucosal immune system. Genital piercing may have facilitated spread of the human papillomavirus into the urethra.
