Actinomycosis of the tongue. A diagnostic dilemma.

Actinomycosis of the tongue is an uncommon form of this well known but little seen bacterial disease. A review of the literature is presented and a report of a case which is believed to be the first from the British Isles in recent years. The clinical appearance mimicked a deep seated malignant tumour with induration, limitation of tongue movement and pain. A Tru-Cut biopsy was obtained which revealed a diagnosis of actinomycosis. Treatment was with oral phenoxymethylpenicillin for 3 months.
