Cutaneous actinomycosis

Cutaneous actinomycosis is a chronic disease that affects the deep subcutaneous tissue of the skin. Caused by an anaerobic, Gram-positive, filamentous type of bacteria in the genus Actinomyces,[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]
