Diagnosis of actinomycosis depends on positive culture or identification of Actinomyces colonies and sulfur granules in histological specimens. In our case, a mass had been growing in the mandible for eight months. The mass appeared to be malignant, both clinically and radiologically. A histopathological examination of the mandible revealed actinomycosis. It should be noted that actinomycosis can mimic a malignancy, and for differential diagnosis, bone biopsy or fine-needle aspiration should be performed pre-operatively.eninfo:eu-repo/semantics/openAccessCervicofacial ActinomycosisPathologyMandibleArticle333N/AQ325625825301047257445287042WOS:000414649900012
