Condyloma acuminatum, a benign disease caused by a filtrable virus, occurs predominantly in the perianal and genital areas. The lesions are nonivasive but are subject to recurrence. In rare instances, a more aggresive form of this disease, known as "giant condyloma acuminatum" or "Buschke-Lowenstein tumor", occurs. In this form, infiltration of the lesion into surrounding structures takes place. This tumor has been reported to occur principally in the genitourinary tract. The authors experienced a case of giant condyloma acuminatum originating from rectum in 67 years old male patient which recurred 3 months after electrofulguration.
