title: Anal carcinoma arising from condyloma acuminata.
abstract: Condyloma acuminata is a common anorectal condition that frequently requires surgical evaluation and treatment. We have noted an increased incidence of anal carcinoma in patients with condyloma acuminata. The purpose of this study is to review the incidence of malignant transformation of condyloma in our recent experience. We conducted a 5-year retrospective review of patients with condyloma acuminata treated at a university medical center that serves as a major referral center for the state. From May 1994 through May 1999 257 patients were treated for anal condyloma. During the same time period 74 patients were diagnosed with squamous cell carcinoma of the anus; nine of these patients also had condyloma acuminata (12.2% of patients with anal carcinoma). All nine were immunosuppressed by illness and/or medication. The extent of carcinoma at diagnosis ranged from stage 0 (carcinoma in situ) to stage IVb. Overall 3.5 per cent of patients with condyloma acuminata also had squamous cell carcinoma of the anus. One patient with stage IVb disease died shortly after initial evaluation. Two patients with advanced disease required extensive surgical intervention and had complex postoperative courses. Malignant transformation of condyloma acuminata may be increasing in incidence. This disease progression can be insidious and may be fatal. Screening of high-risk patients might be of value, and more aggressive early management of condyloma may prevent the development of malignancy.
