Condyloma acuminata of the bladder in benign prostatic obstruction: Case report and review of literature.

ABSTRACT

Condyloma acuminata (CA) is a warty lesion caused by the sexually transmitted human papillomavirus that most commonly affects external genitalia and mucocutaneous junctions. Involvement of the urinary tract (UT) is rare. Anogenital CA is considered a predisposition for urethral and subsequently bladder involvement. Isolated urinary bladder involvement is thought to be due to immunosuppression. A 60-year-old man presented with progressively worsening lower UT symptoms, which culminated in acute urinary retention due to histologically proven benign prostatic obstruction (BPO). He had neither cutaneous nor anogenital CA, and viral markers were unremarkable. He had failed a trial of voiding without catheter and had simple prostatectomy 2 years later. Findings at surgery included an enlarged prostate with prominent median lobe and a sessile, warty lesion of 1.2 cm in the widest diameter found incidentally at the dome of the bladder, which turned out to be CA after histopathological analysis of excisional biopsy specimen. CA of the urethra is uncommon while that of the bladder is rare. CA of the bladder without preceding anorectal CA or immunosuppression is uncommon. There is no report of CA of the bladder in BPO till date. Complete surgical excision is the preferred option of management except when not practicable.
