Actinomyces abscess mimicking mandibular bone cyst

A radiolucent, well demarcated right mandibular bone lesion with a clinical presumptive diagnosis of solitary bone cyst was surgically excised in a 60 year old woman. The histopathologic examination revealed Actinomyces colonies surrounded by chronic granulation tissue. This presentation is unique due to its completely encapsulated abscess formation rather than the more common fistula formation seen in Actinomyces lesions.
