Atypical presentations of pediatric actinomycosis: report of a case.

It is well recognized that cervicofacial actinomycosis is rare in children, especially at maxilla. Actinomycosis involving the maxilla usually is seen as a localized intraoral infection in contrast to classical cervicofacial actinomycosis. In this article, we describe an 8-year-old patient who had actinomycosis involving the bone at the left maxillary lateral incisor region. The diagnosis was based on histologic report because of location and development of the lesion with unusual history. The treatment of choice was removal of the soft and hard tissues with concomitant prolonged penicillin administration. In cases of persistent oral infection the diagnosis of actinomycosis should be actively attempted through microbiologic and histologic examination.
