ABSTRACT
Actinomycosis is an uncommon, chronic, bacterial infection that induces both suppurative and
a granulomatous inflammation. Localized swelling with suppuration, abscess formation, tissue
fibrosis, and draining sinuses characterize this disease. The infection spreads contiguously
forming often draining sinuses that extrude characteristic but not pathognomonic “sulfur
granules.” Infections of the oral and cervicofacial regions are most common; however, any site
in the body can be infected. Other regions that are often affected are the thoracic region,
abdomino-pelvic region, and the central nervous system (CNS). Musculoskeletal and dissemi-
nated disease can also be rarely seen.
