Urethral condyloma acuminata following urethral instrumentation in an elderly man

A 70-year-old man had undergone urethral dilatation with bougie for 8 months following transurethral resection of the prostate and complained papillary masses at the urethral meatus. Physical and endoscopic examination revealed multiple tumors from the urethral meatus to the bulbous urethra. These tumors were resected transurethrally and 5-FU cream was instilled into urethra. Microscopic examination revealed urethral condyloma acuminata. Human papillomavirus types 6/11 were detected in the condylomas. As high prevalence rate of genital human papillomavirus was reported in penile skin of healthy men, urethral instrumentation including transurethral surgery might cause dissemination of penile skin human papillomavirus into the urethral lumen.
