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).
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 ]
Between 60% and 90% of the other cancers listed above are also linked to HPV. [7] HPV6 and HPV11 are common causes of genital warts and laryngeal papillomatosis. [1] 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]
Papillomas caused by some types, however, such as human papillomaviruses 16 and 18, carry a risk of becoming cancerous. [6] Papillomaviruses are usually considered as highly host-and tissue-tropic, and are thought to rarely be transmitted between species. [7] Papillomaviruses replicate exclusively in the basal layer of the body surface tissues.
Laryngeal papillomatosis, also known as recurrent respiratory papillomatosis (RRP) or glottal papillomatosis, is a rare medical condition in which benign tumors form along the aerodigestive tract. [1] [2] There are two variants based on the age of onset: juvenile and adult laryngeal papillomatosis. [3]
Intraductal papillomas of the breast are benign lesions with an incidence of approximately 2-3% in humans. [1] They result from abnormal proliferation of the epithelial cells lining the breast ducts. [2] Two types of intraductal papillomas are generally distinguished. The central type develops near the nipple.
Malignant acanthosis nigricans may also become evident, many times with the sudden eruption of multiple seborrheic keratoses, known as the sign of Leser-Trélat. [ 9 ] [ 10 ] [ 11 ] Florid cutaneous papillomatosis mandates a search for an underlying malignancy, recognizing that it may be seen in patients with multiple visceral carcinomas.
HPV+OPC presents in one of four ways: as an asymptomatic abnormality in the mouth found by the patient or a health professional such as a dentist; with local symptoms such as pain or infection at the site of the tumor; with difficulties of speech, swallowing, and/or breathing; or as a swelling in the neck (if the cancer has spread to lymph nodes).
