Pleomorphic adenomas arise most commonly in the major salivary glands; the minor salivary glands are affected in only 8% of the cases. Intranasal pleomorphic adenoma being extremely rare originates most commonly from the nasal septum. We present a case of a 55-year-old man who presented with complaints of right-sided nasal obstruction and occasional nasal bleed for the last 6 months. Examination showed a mucosa-covered, fleshy 2 x 2 x 1.5 cm mass in the right nasal cavity. Computed tomogram showed right-sided polypoidal mass with attachment to the cartilaginous nasal septum without any erosion of the surrounding structures. The clinical presentation, gross and microscopic appearance, and treatment of intranasal pleomorphic adenoma is briefly discussed.
