Abstract
Schneiderian papillomas are papillomas arising in the sinonasal tract, which is lined with Schneiderian epithelium, ectodermally derived respiratory mucosa [1,2]. This distinctive epithelium can give rise to three histologically unique types of papillomas: exophytic (fungiform, septal, and squamous), inverted (inverting), and oncocytic (cylindrical cell and columnar) papillomas. Exophytic papillomas almost exclusively arise from the nasal septum with rare cases arising from the vestibule or middle turbinate. In this paper a case of Exophytic papilloma in 52 year old male is presented.
