Actinomycosis is a chronic suppurative infection that can occur in the head and neck region. Though cervico-facial actinomycosis is well described, primary actinomycosis of the salivary gland is rare and can present as any other suppurative infection or can simulate malignancy. We hereby report a case of a young male with primary actinomycosis of submandibular gland, presenting as acute suppurative infection and diagnosed on histopathology.
