Also known as lingual tonsil squamous cell carcinoma (SCCa)
Epithelial tumor of epidermoid origin arising in the lingual tonsilar area of the oropharyngeal mucosal space
Lingual tonsils are part of the Waldeyer lymphatic ring located just posteriorly to the circumvallate papilla of the tongue
Symptoms from this tumor occur late, so tumor is often large (>4 cm) at presentation
Lesion can either be exophytic, invasive, or both
Anterior: sublingual space, oral tongue root, or floor of mouth
Posteriolateral: anterior tonsillar pillar
Inferior: supraglottic larynx and hypopharynx space
On CT: Mucosal asymmetry and moderate enhancement with contrast, difficult to assess superficial spread, deep spread easily noted
On MR: On T1 lesions are isointense to muscle and spread easily noted; on T2 lesions are iso- to hyperintese; post-contrast T1 shows enhancement
Smoking and alcohol are known risk factors
Most common nodal involvement is level II nodes
Men and those over 40 are most commonly affected
Lungs more so than bones more so than liver are the organs where metastasis is most commonly noted
