A Case of Submandibullar Sialolithiasis due to Actinomycosis / 대한이비인후과학회지

ABSTRACT

Actinomycosis is an uncommon disease caused by actinomyces species, which are gram-positive anaerobic bacteria with filamentous appearance. Actinomyces israelii is the most common pathogen resulting in actinomycotic infection. The infection usually presents 3 distinct localizations cervicofacial, thoracic, abdomino-pelvic. Cervicofacial actinomycosis accounts for about 50% of the cases. The sulfur granule defines the pathognomic pathologic finding of actinomycosis, but it has been reported in only 40% of cases. We report on a case of submandibular sialolithiasis that occurred due to antinomycosis in a 50-year old male patient.
