Squamous cell papilloma of the mouth or throat is generally diagnosed in people between the ages of 30 and 50, [1] and is normally found on the inside of the cheek, on the tongue, or inside of lips. Oral papillomas are usually painless, and not treated unless they interfere with eating or are causing pain. [1]
It is caused by the human papilloma virus types 13 and 32. [3] It exhibits surface cells with vacuolated cytoplasm around irregular, pyknotic nuclei and occasional cells with mitosis-like changes within otherwise mature and well-differentiated epithelium. A distinguishing histologic feature is elongated rete ridges with mitosoid bodies.
The origin of the lesion is unclear. This condition appears to be of an inflammatory nature. [7]An excessive denture palatal relief area, creating a void between the denture base and the tissue of the palate, encourages food entrapment and so encouraging bacterial and fungal growth between the two surfaces.
A papilloma (plural papillomas or papillomata) (papillo-+ -oma) is a benign epithelial tumor [1] growing exophytically (outwardly projecting) 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 (such as the nipple).
An HPV infection is caused by the human papillomavirus, a DNA virus from the papillomavirus family. [8] [9] Over 200 types have been described. [10] An individual can become infected with more than one type of HPV, [11] and the disease is only known to affect humans.
Papillomas and warts/verrucae: They are caused by various strains of the human papilloma virus (HPV) of which there are more than 100 strains but usually due to HPV types 6 and 11. Papillomas are mostly spiky, finger like projections, or cauliflower head rounded lobular shaped. Usually painless and singular. Verrucae usually appear on the lips.
Transient lingual papillitis is generally diagnosed based on patient presentation, meaning where it is located in the mouth and how big the bump is. [8] The visual presentation can also accompany various signs and symptoms such as difficulty eating, having a "strawberry tongue", increased saliva production, and a burning or tingling sensation. [9]
Human papilloma virus (HPV), especially HPV 16 and 18, [1] is sometimes found in areas of leukoplakia, however, since this virus can be coincidentally found on normal, healthy mucosal surfaces in the mouth, it is unknown if this virus is involved in the development of some leukoplakias.
