Cutaneous actinomycosis is achronic disease that affects the deepsubcutaneous tissue of the skin. Caused by ananaerobic, Gram-positive, filamentous type ofbacteria in the genusActinomyces,[1]: 270 invasion of the soft tissue leads to the formation of abnormal channels leading to the skin surface (external sinus tracts) that discharge pale yellow sulfur granules.[2]
This disease is uncommon, and has non-specific clinical features, making it difficult to diagnose.[3]
Cervicofacial, pulmonary/thoracic and gastrointestinal forms exist, yet cervicofacial disease accounts for two-thirds of reported infections.[4]
