Naso-Septal Tuberculosis Mimicking Dermoid in a 3-Year old Child.

Introduction: Tuberculosis is a communicable disease caused by mycobacterium tuberculosis that primarily affects the lungs. Primary tuberculosis of the nose in the pediatric age group is rare. The diagnosis of this common entity in the present case was challenging.

Case Report: We report the case of a 3-year old girl who presented with a painless swelling over the dorsum of the nose for 7 months. Imaging revealed a mass lesion eroding nasal bones, septum and frontal bone with intracranial extension. Endoscopic examination showed a friable mass in the superior aspect of the nasal septum, extending intracranially. Histopathology confirmed the diagnosis of nasal tuberculosis, and the patient improved on category I anti-tubercular therapy.

Conclusion: Midline nasal swelling in children needs to be differentiated from congenital nasal swelling. A high index of suspicion is required for correct diagnosis of a patient with nasal tuberculosis. Anti-tubercular therapy is the mainstay of treatment.
