It is most frequently caused by *Actinomyces israelii* or related filamentous, anaerobic to microaerophilic Gram-positive bacteria that normally inhabit the oral cavity as commensal flora The condition is clinically characterized by a slowly enlarging, woody, indurated swelling—often termed "lumpy jaw"—that progressively crosses tissue planes and forms abscesses, draining sinus tracts, and purulent exudates containing macroscopic sulfur granules
