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).
Because HPV type 16 is the most common type found in oropharyngeal cancer, p16 immunohistochemistry is one test option used to determine if HPV is present, [135] which can help determine course of treatment since tumors that are negative for p16 have better outcomes.
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 ]
[3] [4] [5] Infection by most papillomavirus types, depending on the type, is either asymptomatic (e.g. most Beta-PVs) or causes small benign tumors, known as papillomas or warts (e.g. human papillomavirus 1, HPV6 or HPV11). Papillomas caused by some types, however, such as human papillomaviruses 16 and 18, carry a risk of becoming cancerous. [6]
Cases of PB have also been reported to occur in individuals with a family history of certain genetic diseases. [4] Pediatric cases of PB tumors are commonly treated by total resection. [6] Complete excision of PB tumors with clear surgical margins to remove all tumor cells is important in order to reduce a recurrence of the tumor at its site of ...
Papillary carcinomas of the breast (PCB), also termed malignant papillary carcinomas of the breast, are rare forms of the breast cancers. [1] The World Health Organization (2019) classified papillary neoplasms (i.e. benign or cancerous tumors) of the breast into 5 types: intraductal papilloma, papillary ductal carcinoma in situ (PDCIS), encapsulated papillary carcinoma (EPC), solid-papillary ...
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]
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.
