A case of solitary neurofibroma of the nasal dorsum: resection using an external rhinoplasty approach.

A 7-year-old girl had suffered from progressive swelling of the nasal dorsum over 2 years. Computed tomography and magnetic resonance imaging showed a large soft tissue density in the nasal dorsum. Tc-99m DTPA cisternography and brain SPECT showed a restricted mass in the nasal dorsum without intracranial connection. The mass was resected using an external rhinoplasty approach, and the pathologic diagnosis was of neurofibroma. Furthermore, the nasal dorsum was identified as the origin of the neurofibroma without the stigma of neurofibromatosis. Here, we present this case and discuss the clinical and pathological aspects of neurofibroma arising in the nasal dorsum.
