Abstract
Actinomycosis is characterised by the chronic, suppurative and cellulitic invasion of soft tissues primarily caused by the bacteria genus Actinomyces. Due to unique anatomical and histophysiologic features of the tongue, lingual actinomycosis is an extremely rare finding. Without proper diagnosis and treatment, it may cause extensive tissue damage. The authors report on an unusual case of lingual actinomycosis in the hopes of aiding the present and future dental practitioners in diagnosing the lesion correctly for appropriate specialist referral and management.
