Mandibular actinomycosis

Abstract

Introduction Actinomycosis is a rare disease. The cervicofacial region is the most frequent localization. A chronic pus discharge, sometimes tumor-like, suggests the diagnosis, which is often confirmed by anatomopathology. The treatment is surgical debridement and antibiotic therapy, frequently long-term. We report three cases of mandibular actinomycosis. Case reports A 21-year-old male patient presented with a fistulized swelling of the right jaw. A 48-year-old male patient was referred for alveolar healing delay after avulsion of teeth 32, 33, and 34. A 38-year-old female patient presented with a left mandibular swelling and restricted mouth opening. In the three cases, the diagnosis of actinomycosis was made by histology. The clinical outcome was good following alveolar curettage (and sequestrectomy for 1 patient) and antibiotic therapy. Discussion Mandibular actinomycosis is caused by Actinomyces israelii. Lesions if untreated may evolve to osteitis and sequestration. Early diagnosis is crucial. © 2013 Published by Elsevier Masson SAS.
