Papillomas of The Nose and Paranasal Sinuses

Abstract

Papillary intranasal tumors in 21 cases were subdivided into inverted papillomas and septal papillomas, and the validity of such a subdivision is discussed, as is their relation to inflammatory polyps. Both papillomas may recur over a period of many years; however, there appears to be no significant tendency for malignant change with repeated recurrence. Histologic malignant change arising in inverted papillomas is present at the outset or very early in the clinical course, yet does not indicate a hopeless prognosis. Optimal therapy for these lesions is total excision of intranasal and sinusal components. These lesions are often histologically over-diagnosed, and pitfalls in microscopic interpretation are indicated. The papillomas are considered to be benign neoplasms, histologically, microscopically, and etiologically distinct from inflammatory polyps.
