Actinomycosis in darker-skinned individuals often presents as painful, swollen, and abscessed areas with draining sinuses, typically affecting the jaw, neck, or chest, with the skin appearing red, purple, or brown. The condition is caused by the bacteria *Actinomyces*, which can lead to chronic infections if left untreated, sometimes resulting in tissue fibrosis or scarring. Treatment involves prolonged antibiotic therapy, often with penicillin, and surgical drainage may be necessary for abscesses to prevent further complications.
