[Anal condylomata acuminata. A prospective comparison of HIV positive and negative patients]

Between July 1986 and May 1987 23 patients suffering from anal condylomata acuminata were treated at the University Hospital of Zurich. The influence of HIV-infection on the disease is described. An almost equal frequency of recurrencies between positives and negatives was observed in a three year follow-up time. However, in positive patients recurrence was earlier and much more extensive. A two-stage procedure which sometimes is advocated in very extensive lesions gave very bad results in HIV positives. We use a radical excision by electrocoagulation on the mucosa and perianally and avoid circular necrosis in the lower anal canal only. Infectious complications are not to be feared except in patients with symptomatic HIV-infection resulting in the recommendation for a antibiotic prophylaxis in such cases.
