Endoscopic submucosal dissection of an anorectal Condyloma acuminatum.

Condyloma acuminatum (CA) is a common sexually transmitted disease caused by human papilloma virus infection. Although it is generally seen in the genital and perianal regions, anal canal and rectum sometimes could be involved. It has been reported to be associated with higher risk of intraepithelial neoplasia and cancer. Surgery excision and fulguration are the primary treatment, while high local recurrence rate of CA remains bothering. We presented a case of CA that detected via colonoscopy and successfully treated with endoscopic submucosal dissection.
