A papilloma is a benign epithelial tumor growing exophytically in nipple-like and often finger-like fronds. In this context, papilla refers to the projection created by the tumor, not a tumor on an already existing papilla.
Signs and symptoms

Neither sex is significantly more likely to develop papillomas. The most common site is the palate–uvula area, followed by tongue and lips. Durations range from weeks to 10 or more years. ==Presence of HPV==

Immunoperoxidase stains have identified antigens of the human papillomavirus (HPV) types 6 and 11 in approximately 50% of cases of squamous cell papilloma. ==Prognosis==

Papillomas are benign epithelial lesions commonly associated with human papillomavirus (HPV), while certain HPV types are linked to cancer development. ==Differential diagnosis==
