We report a rare case of fibro-hyaline anterior extensions of the bony nasal pyramid.
The clinical, radiological, intra-operative and histological findings are presented.
A 34-year-old man presented with bilateral nasal obstruction due to enlarged lateral walls of the nasal vestibule. Radiology showed normal bony structures. Surgery revealed three histologically identical, non-malignant, fibrous masses, one in the nasal septum and one in each of the vestibular walls. The latter were attached to the bony pyramid, protruding anteriorly and converging medially.
The location and symmetry of the fibro-hyaline projections indicated that they constituted a malformation mimicking congenital bony nasal pyriform aperture stenosis. Histological analysis showed that the masses were not neoplastic.
