Lingual sebaceous glands: report of case.

A 28-year-old dentist noticed a 9X5-mm yellow submucosal plaque in the midlateral dorsum of his tongue. After a period of observation an excisional biopsy was performed. The histopathologic examination of the specimen revealed normal sebaceous glands opening onto the tongue surface. This occurrence of ectopic sebaceous glands in the tongue is notably rare in contrast with their frequent occurrence in the lips and buccal mucosa.
