A 29-YEAR-OLD white woman presented with a 1½-year history of a gradually enlarging mass involving the left side of the bridge of her nose. The mass was not associated with epistaxis, rhinorrhea, or nasal obstruction, and the patient had no history of nasal trauma or previous surgery. On examination, a firm, spherical, 1-cm, noncompressible mass was identified over the superior aspect of the left nasal bone. It was minimally tender to palpation. Intranasal examination with the 0° and 30° telescope revealed a convex swelling in the superior aspect of the left nose. The overlying mucosa was intact. The results of the rest of her head and neck examination were unremarkable.
