Correct answer: B — Cervicofacial actinomycosis with sinus tracts draining 'sulfur granules'
Cervicofacial actinomycosis is a chronic bacterial infection caused by Actinomyces israelii (a Gram-positive, anaerobic, filamentous bacterium). It is characterised by a firm swelling (classically perimandibular), sinus tract formation draining purulent material containing yellow 'sulfur granules' (colonies of organisms), and a tendency to cross tissue planes ignoring anatomical barriers. It typically follows dental extraction trauma or surgery. Treatment is prolonged high-dose penicillin (or amoxicillin) for 2-6 months.
