title: Cervicofacial actinomycosis mimicking sebaceous cyst.
abstract: Actinomycosis is a rare, torpid, suppurative and chronic granulomatous infection caused by a Gram-positive organism that was initially thought to be a fungus. These organisms normally live as commensals in the human oral cavity, respiratory and digestive tracts, but become invasive when they gain access to the subcutaneous tissue through a musosal lesion, the triggering events being dental caries, dental manipulation and maxillofacial trauma. It is often misdiagnosed as it can mimic numerous infectious and non-infectious diseases. We describe an interesting case of cervical actinomycosis that was misdiagnosed as sebaceous cyst and precisely identified after histopathological examination of the tissue.
