Extracranial meningiomas are rare in children and are frequently misdiagnosed. We report a case of primary extracranial meningioma of the nasal cavity in a 2-year-old child who presented with a recurrent, gradually increasing swelling over the nasal bridge. Computed tomography scan revealed a mass protruding through a rent in the nasal bridge. Fine-needle aspiration cytology showed features suggestive of a benign mesenchymal neoplasm. Histologically, a diagnosis of meningothelial meningioma was made which was confirmed by immunohistochemistry. The neoplastic cells were strongly positive for vimentin and epithelial membrane antigen, weakly positive for S-100 and negative for neuron specific enolase, and glial fibrillary acidic protein. The case is documented for the rarity of its occurrence and varied prognosis.
