Two unusual presentations of cervicofacial actinomycosis and review of the literature Due casi di actinomicosi cervico-facciale a localizzazione inusuale e revisione della letteratura

Summary Cervicofacial actinomycosis is the most common clinical form of actinomycosis. This bacterial infection is rare. Diagnosis is difficult, often it is definitive only after surgical excision of the cervicofacial mass. Personal experience is reported concerning two cases of cervicoactinomycosis. Diagnosis, in both cases, has been based on histological findings, not on clinical symptoms. A review of the literature shows that mainly males are affected by this condition and, in fact, both patients described here are males. Symptoms of acute infection were absent. Both patients denied any history of oromaxillofacial trauma or recent dental extraction or oral manipulations. Imaging techniques – ultrasonography and computerized tomography – were not effective in making the diagnosis, in either of these patients. Furthermore, fine needle aspiration cytology did not provide a definitive diagnosis. Both patients underwent surgical excision of the mass. Penicillin was the drug of choice in post-operative long-term treatment (one month). In one of the two men, intravenous steroids were administered. As in several reports in the literature, the definitive diagnosis was histological and not clinical.
