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.

Actinomycosis is a disease caused by an anaerobic bacteria called Actinomyces species (predominantly Actinomyces israelii), which is a common and normally nonpathogenic organism found in the nose and throat. The four major clinical presentations of actinomycosis include the cervicofacial, thoracic, abdominal, and pelvic region. Actinomycosis is difficult to diagnose because of variable presentation and fastidious nature of the organism in culture. A high index of suspicion and biopsy are often necessary to make the diagnosis, because the disease can mimic neoplasm or a chronic granulomatous infection. We present, with the appropriate review, a case of actinomycosis in the mandibular angle area which was mistaken for a parotid abscess.

Actinomycosis of cerivcofacial region is an uncommon disease and presents as an abscess or chronic lesion mimicking malignancy, tuberculosis, or fungal lesion. Actinomycosis is difficult to diagnose because of fastidious nature of the organism in culture and general lack of familiarity with the disease. So, a high index of suspicion is required to make an accurate and timely diagnosis. We present a case of male patient with actinomycosis of submandibular triangle complaining of neck mass.
