Primary Nasopharyngeal Tuberculosis: A Diagnostic Challenge.

Introduction: Primary nasopharyngeal tuberculosis (NPTB) is a rare disease but should not be missed as one of the differential diagnoses for cervical lymphadenopathy or nasopharyngeal mass.

Case report: We describe a case of a 38 year old lady, who presented with bilateral cervical lymphadenopathy associated with intermittent fever. Nasoendoscopy examination and computed tomography scan of the neck revealed a centrally located mass predominantly at the left posterior nasopharyngeal wall without obliteration of both fossae of Rosenmuller. Typical histopathological features of necrotizing granulomatous lymphadenitis together with the common clinical presentation of cervical lymphadenopathy and nasoendoscopy findings of nasopharyngeal mass conclude the diagnosis of nasopharyngeal tuberculosis. With anti-tuberculous therapy, the cervical lymphadenopathy and nasopharyngeal mass were completely resolved.

Conclusion: Nasopharyngeal tuberculosis is an uncommon disease with great diagnostic challenges and with early diagnosis and adequate treatment, NPTB carries a good prognosis with complete disease resolution.
