Papillary hyperplasia often arises in the mucosa of the tongue, palate, lip, cheek, and gingiva but very rarely in the uvula. This paper describes a case of papillary hyperplasia arising in the tip of the uvula. A 59-year-old male was referred to our clinic complaining of a mass in the tip of the uvula. It was discovered by the patient ten years earlier. A 13mm diameter tumor resembling a pedunculated polyp was found in his uvula. Upon the clinical diagnosis of benign tumor, it was removed under local anesthesia. The lesion was diagnosed as papillary hyperplasia. Human papillomavirus (HPV)-DNA were examined using a molecular biological method. HPV-DNA was present, but the type of HPV could not be determined. There has been no clinical evidence of recurrence for four years.
