Sebaceous choristoma of the thyroglossal duct.
The presence of sebaceous glands within the oral mucosa is not uncommon. Such Fordyce granules are frequently seen on the buccal mucosa and lips, as well as in the retromolar area, gingiva, and palate. Whereas sebaceous elements are rarely encountered on the tongue, three cases of ectopic sebaceous glands have been reported in association with apparently patent thyroglossal ducts. An interesting case of a previously unreported sebaceous choristoma of the thyroglossal duct is described.
