Actinomycosis is an infectious disease that can involve the cervicofacial region, however infection of the tongue is extremely rare. We report a 44-year-old man with poorly controlled diabetes mellitus who developed actinomycosis of the tongue. He complained of odynophagia and pain of the tongue which demonstrated thick fur over the median ulcer. The lesion was diagnosed actinomycosis of tongue based on typical histopathological findings.
