Comment:

Actinomycosis should be considered in the differential diagnosis of any acute, subacute, or chronic cutaneous swelling of the head and neck. The cervicofacial form of Actinomycetes infection is the most common presentation, typically as an acute pyogenic infection in the submandibular or paramandibular area, but infection could be elsewhere in the mandibular and maxillary regions. The primary skin infection may spread to adjacent structures such as the scalp, orbit, ears, and other areas. Oral infection may spread to the hypopharynx, larynx, trachea, salivary glands, and sinuses. Actinomycosis can spread beyond boundaries of tissue planes and may also mimic chronic osteomyelitis. Treatment consists of a combination of penicillin therapy and surgical debridement. Debulking and debriding infected tissue arising from sinus tracts and abscess cavities inhibit actinomycosis growth in most cases.
