Abstract
Introduction: Nasal dermoid sinus cysts are rare congenital anomalies that account for 1% of dermoid cysts. They typically present as midline nasal lesions and may involve intracranial structures.
Observation: A 17-year-old female presented with a congenital midline nasal bridge nodule, which became noticeable during adolescence due to coarse dark hairs. Clinical examination revealed a well-defined nodule with a hyperpigmented patch inferiorly. MRI confirmed the absence of intracranial extension. The lesion was surgically excised, resulting in satisfactory cosmetic and functional outcomes.
Conclusion: This case highlights the importance of including nasal dermoid sinus cysts in the differential diagnosis of midline nasal lesions. Imaging is essential for preoperative planning to assess intracranial involvement and guide safe surgical management.
