ICD-11 definition : Cervicofacial actinomycosis is the commonest clinical form of actinomycosis, a sporadically
occurring endogenous polymicrobial inflammatory process in which fermentative actinomycetes
of the genera Actinomyces (especially A. israelii and A. gerencseriae), Propionibacterium
and Bifidobacterium act as the principal pathogens. The typical presentation is a
slowly progressive development from painless tissue infiltration and induration of
soft tissues of the face and neck to multiple abscesses and draining sinus tracts
discharging pus. Actinomycosis is a major factor and indicator of poor prognosis in
infected osteoradionecrosis of the jaws following head and neck cancer therapy.;
