[Leukoplakia of the anal verge with bleeding hemorrhoids. A case report].

We present a case of a 45-year-old patient who reported bleeding hemorrhoids. He had grade II hemorrhoids and was found to have a circumferential leukoplakic lesion at the anal verge. The patient had no symptoms of leukoplakia. The hemorrhoids were ablated with an Ellman radiowave device. Histological findings of the incised lesion from the verge showed hyperkeratosis and acanthosis extending cephalad from the anal verge to the dentate line. Follow-up after 5 years revealed no evidence of dysplastic changes in the leukoplakic lesion. Because of the varied opinions regarding the fate of leukoplakia of the anal canal, patients should be followed carefully to detect any malignant transformation of the lesion.
