The aim of this study was to evaluate anal pathology in men having sex with men (MSM) seen at our proctology outpatient clinics.


The charts of 74 MSM treated by the author between January 2002 and April 2006 were reviewed.


Three of 74 patients (4%) had proctitis and 96% had anogenital condylomata acuminata (warts). 49 out of 71 (69%) had external anogenital as well as intra-anal warts and 13 (18%) had only intra-anal warts. In 14 an intra-anal dysplasia and in 2 patients intra-anal verrucous carcinomas were detected. The average duration of disease before referral to our institutions was more than 9 months. Half of the patients were previously treated for anogenital warts with ointments and suppositories at other institutions, including 17 that were "treated" with ointments and/or suppositories for hemorrhoids prescribed by family physicians. The patients mostly had widespread disease and sixty-nine of them required surgery. In the follow-up period there was no recurrence of warts and only itching was observed in 31 (44%) patients. Therapy with imiquimod was introduced for 3 months in twenty-two cases with intra-anal dysplasia. No major side effects were noticed despite intra-anal use.


Proctoscopy and histological examination of intra-anal lesions in cases of external anogenital warts should be mandatory in MSM patients. I would like to encourage other physicians to use this approach, which enables detection of intra-anal warts, dysplasia, and even carcinoma in the asymptomatic stage.
