Cylindrical Cell Papilloma of the Maxillary Sinus

Abstract

The cylindrical cell papilloma is considered to be a form of Schneiderian nasal papilloma. This form of papilloma is rare. There are clinical and histologic differences between an ordinary inverting papilloma and a cylindrical cell papilloma. Both forms of papillomas present as ragged or papillary growths in the maxillary sinus or in conjunction with lesions of the adjacent lateral nasal wall or ethmoid sinus. An unusual case of cylindrical cell papilloma and a review of the literature concerning this lesion is presented. Magnetic resonance imaging (MRI) scan is advantageous in evaluating this lesion, especially in distinguishing these lesions from cysts and in defining the extent of the problem. Medial maxillectomy via lateral rhinotomy or a facial degloving approach partial maxillectomy is usually curative for this problem, although more aggressive lesions require more extensive maxillectomy.
