Carcinoma of the tonsil is a type of squamous cell carcinoma. The tonsil is the most common site of squamous cell carcinoma in the oropharynx. It comprises 23.1% of all malignancies of the oropharynx. [1] The tumors frequently present at advanced stages, and around 70% of patients present with metastasis to the cervical lymph nodes. [2].
Oropharyngeal cancer, [1] [2] [3] also known as oropharyngeal squamous cell carcinoma and tonsil cancer, [1] is a disease in which abnormal cells with the potential to both grow locally and spread to other parts of the body are found in the oral cavity, in the tissue of the part of the throat that includes the base of the tongue, the tonsils, the soft palate, and the walls of the pharynx.

Specialty: Oncology, oral and maxillofacial surgery: Risk factors: Alcohol, tobacco, betel quid, human papillomavirus, radiation exposure, certain workplace exposures, Epstein–Barr virus [1] [2] Diagnostic method: Tissue biopsy [1] Prevention
A survey of 23 countries between 1983 and 2002 showed an increase in oropharyngeal squamous cell carcinoma that was particularly noticeable in young men in economically developed countries. [220] [12] In the United Kingdom the incidence of oral and oropharyngeal cancer in men rose 51%, from 7/100,000 to 11/100,000 between 1989 and 2006. [233]
Squamous-cell carcinoma (SCC), also known as epidermoid carcinoma, comprises a number of different types of cancer that begin in squamous cells. [1] These cells form on the surface of the skin, on the lining of hollow organs in the body, and on the lining of the respiratory and digestive tracts .
Oral squamous cell carcinoma is the end product of an unregulated proliferation of mucous basal cells. A single precursor cell is transformed into a clone consisting of many daughter cells with an accumulation of altered genes called oncogenes. What characterizes a malignant tumor over a benign one is its ability to metastasize.
One study found squamous-cell carcinoma of the penis had a much greater rate of mortality than some other forms of squamous-cell carcinoma, that is, about 23%, [65] although this relatively high mortality rate may be associated with possibly latent diagnosis of the disease due to patients avoiding genital exams until the symptoms are ...
Lingual tonsils are covered externally by stratified squamous epithelium (nonkeratinized) that invaginates inward forming tonsillar crypts. Beneath the epithelium is a layer of lymphoid nodules containing lymphocytes. Mucous glands located at the root of the tongue are drained through several ducts into the crypts of the lingual tonsils.
