Cervicofacial actinomycosis: a report of 14 patients observed at the Dermatology Unit of the University of Milan, Italy.

CFA is a rare infection caused by primary lesions in the oral cavity and subsequent fistulae, and nodular and ulcerative lesions on the skin of the face. Clinical diagnosis must be confirmed by histopathologic, bacteriologic, and instrumental examinations. Therapy with penicillins is usually very long and must be accompanied by surgical drainage and debridement of the oral cavity.
