Actinomycosis of the mandible which doubted as parotid gland tumor: Report of a case

Actinomycosis, which is a granulomatous inflammation and difficult to heal, has become reatively rare due to antibiotics. We encountered one case of actinomycosis of the mandible which was suspected to be a parotid gland tumor, because of swelling at the parotid gland region, trismus, and multiple radiolucenies of the mandible. The granulation tissue was removed almost “en bloc” and curreted thoroughly at the resorbed region of the mandible. Pathologically the actinomycetic mass was found in the granulation tissue. For antibiotics, LMOX was given nine days post-operatively, and after diagnosed pathologically, AB-PC was given for twenty-eight days. Now, four years after the operation the patient has satisfactory ossification at his mandible without recurrence.
