Oral papilloma is not normally contagious, but if it is caused by HPV infection, it can be transmitted through close contact such as kissing. Oral papillomas, usually occurring in people aged 11-40 years, can involve any part of the oral cavity, more commonly the soft palate, uvula and tongue. Clinically, they usually present as white or red warty, finger-like, or cauliflower-shaped swellings. The presence of HPV antigens can be detected in approximately 50% of cases, and in some cases may be the result of mechanical irritation. Oral papillomas are largely finger-like protrusions covered with squamous epithelium and may have marked hyperkeratosis, incomplete keratinization or no keratinization under the microscope. HPV-infected dugout cells are seen in the sphenoid epithelium in about 45% of cases. In the clinic, it is usually treated by surgical excision, or excision by laser or freezing techniques, and is generally non-recurring and has no potential for malignant transformation. Patients are advised to develop good habits and avoid undesirable factors to prevent the occurrence of the disease.
