Abstract
Papillomas of the sinonasal tract are uncommon tumors. They can be subdivided into different histopathological entities including inverting papilloma, fungiform papilloma and cylindrical cell papilloma. Cylindrical cell papilloma is one of the rarest with only twenty-three cases reported. This rare histologically distinct variant of papillomas of the sinonasal tract behaves clinically like inverting papillomas. We present what we believe to be the first reported case of a cylindrical cell papilloma isolated to the nasal septum. The patient's pathology and a literature review of cylindrical cell papillomas of the sinonasal tract are presented.
