A Case of Black Hairy Tongue / 대한피부과학회지

ABSTRACT

Black hairy tongue occurs on the dorsum of the tongue, and is characterised by a black, yellowish, or brown plaque with hairlike structures which result from benign hyperkeratosis of the filiform papillae. It may be associated with several conditions such as smoking, oral antibiotics or candida infection. However, the definite etiology is unknown. We report a case of black hairy tongue without any associated condition.
