 A 49-years-old male visited our hospital with the complaint of body weight loss. He was homosexual and had had an experience of anal intercourse. Colonoscopy revealed an elevated lesion, which was an aggregation of nodules of various size, spreading throughout three quarters of the circumference of the lower rectum. The lesion was soft, whitish and slightly reddish in part, and had a granular surface. Histological findings of the biopsy specimen showed condyloma acuminatum, and trasanal surgery was performed. Microscopic findings of the resected specimen showed the wide-spread coexistence of dysplasia with condyloma acuminatum, and a small nest of squamous cell carcinoma in the basal layer. In addition, human papilloma virus(HPV), type 6, was detected by PCR analysis of the biopsy specimen.
