[Six cases of actinomycosis]

Actinomycosis is a rare granulomatosis infection caused by anaerobic bacteria; Actinomyces. There are many locations of actinomycosis and they can simulate an inflammatory or malignant process or pyogenic infection. We report 6 cases of actinomycosis. The diagnosis was confirmed by an anatomopathologic exam. The evolution was marked by an improvement after prolonged antibiotic treatment. This study shows the difficulties in the diagnosis of actinomycosis and the importance of systematic histopathological examination
