Foliate papillae are short vertical folds found on the lateral margins of the tongue. Taste buds, the end-organs of the gustatory sense, are scattered over the mucous membrane of their surface. Serous glands drain into the folds and clean the taste buds. They are occasionally Misdiagnosed as tumors or inflammatory disease. They are usually bilaterally symmetrical. Sometimes they appear small and inconspicuous, whereas they may sometimes be prominent. Lingual tonsils are found immediately beneath the foliate papillae and, when hyperplastic, cause a prominence of the papillae.
Differential Diagnosis
- Hyperplastic lingual tonsils - Squamous carcinoma - Soft tissue tumors
