Background: head and neck actinomycosis is an infectious disease due to a bacterium actinomyces israelii (AI), nasopharyngeal localization is exceptional. Case presentation: In this study we report a case of a 15-year-old male patient with no history of nasal mucosal breaks consulting for a neck lymphadenopathy with nasopharyngeal discomfort. The endoscopy revealed a mass of the nasopharynx, biopsy and anatomopathological study confirmed a nasopharyngeal actinomycosis. The patient was treated with a prolonged course of penicillin (45 days) which resulted in successful resolution of his condition. Discussion and Conclusion: Nasopharyngeal Actinomycosis is a rare bacterial infection that usually develops following nasal trauma or surgery. Happening without prior trauma make the diagnosis challenging and the physiopathology unclear.
