Buschke-Loewenstein tumour infiltrating pelvic organs.

Abstract

We report a 42-year-old HIV-negative patient with a 12-year history of exceptionally extensive genital warts and coexisting verrucous carcinoma of the anogenital region (Buschke-Loewenstein tumour). Masses of both tumour and viral papillomas infiltrated the external genitalia, perineum and buttocks, pelvic diaphragm and parts of the lesser pelvis, as well as the urethra, prostate and parts of the urinary bladder, necessitating repeated surgical intervention and plastic reconstruction. Adjuvant interferon-alpha therapy was given without any lasting effects. Human papillomavirus type 6 was detected by DNA in situ hybridization and Southern blot analysis.
