Squamous papilloma of the oral cavity is an HPV-driven lesion, most often related to HPV types 6 and 11.
Lesions may arise in children as well as adults. Any site in the oral cavity may be affected although as in this case, the palate is a favored place for them to arise. A soft pedunculated nodule, which may appear granular due to the papillary fronds, and usually under 1 cm, is observed.
Excision or laser ablation.
