ABSTRACT

Actinomycosis is an infection mainly caused by Actinomyces israeli, which is often part of the normal flora of the oral cavity, other microorganisms that have been linked are A. naeslundii, A. odontolyticus, A. viscosus A. meyeri and, less frequently, the Propionibacterium propionicum. We present the case of a male patient aged 76, who came to dental consultation presenting three erythematous nodular lesions in oral cavity at the upper alveolar ridge, which to exploration were of soft consistency and approximately of 1.5 cm in diameter each. Injuries had one month of evolution, were asymptomatic, and there was history of extraction of root fragments. Histopathology revealed the presence of bacterial colonies surrounded by an intense mixed type inflammatory infiltrate. Actinomicosis conventional therapy is based on a high-dose of intravenous penicillin followed by oral penicillin or amoxicillin for a period generally ranging from six to 12 months. Actinomycosis is a relatively common infection that usually is not considered in the differential diagnosis, we propose to medical and dental staff to suspect this infection in the presence of a painful and persistent nodule in the cervicofacial region where exists a history of tooth extraction and/or trauma. We highlight that a histopathological study is needed to establish the timely and correct diagnosis, which will allow initiating treatment and subsequent resolution of the infectious process.
