Endoscopic Resection of a Posterior Nasal Septum Pleomorphic Adenoma.

A 60 year-old female presented to our clinic with a two-year history of progressive nasal obstruction and one isolated episode of epistaxis that did not respond to medical treatment. Endoscopic evaluation revealed roundish, dumbbell-shape, smooth-surfaced, submucosal mass with prominent vessels of approximately 2 cm in the posterior nasal septum,. A paranasal CT scan revealed a well-circumscribed oval shape mass (1.7 cm x 1.6 x 1.5 cm) arising from the posterior border of the bony nasal septum. The tumor was removed en-bloc with 1-centimeter free margins confirmed by intra-operative frozen sections through a completely endoscopic approach. Pathology results confirmed the diagnosis of a pleomorphic adenoma.
