Actinomycosis of the cheek

Abstract

SUMMARY Introduction Actinomycosis is an uncommon chronic granulomatous infection first described by Bollinger in 1877. The infection is caused by actinomyces species and it is characterized by slow contiguous spread and suppurative inflammation, formation of multiple abscesses and sinus tracts with possible drainage of “sulfur granules”. Case Outline We report an unusual case of actinomycosis of the cheek that occurred 6 years after buccal odontogenic abscess. A 56-year-old male was referred to the Department of Oral Surgery because of a painless swelling of the left cheek, which initiated three weeks prior to the referral. The diagnosis of actinomycosis was confirmed by histopathologic examination. In accordance with the diagnosis oral penicillin was prescribed for four months with complete resolution. Conclusion This case of actinomycosis is presented as a rarity. For proper diagnosis, careful examination and a high degree of clinical suspicion are necessary.
