Fibro-hyaline extensions from the bony nasal aperture, causing nasal obstruction.

摘要

OBJECTIVE: We report a rare case of fibro-hyaline anterior extensions of the bony nasal pyramid. METHOD: The clinical, radiological, intra-operative and histological findings are presented. RESULTS: 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. CONCLUSION: 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.
