A Case of Cylindrical Cell Papilloma Originated from Sphenoid Sinus / 대한이비인후과학회지

Cylindrical cell papilloma, the rarest among papillomas of the sinonasal tract, are subdivided into inverted papilloma, fungiform papilloma and cylindrical cell papilloma. It is characterized by proliferative, multi-layered columnar cells and has the clinical features of an inverted papilloma. It usually originates from the lateral nasal wall and sinuses (mainly maxillary and ethmoid sinus). With a review of literature, we report a case of a 47-year-old male with cylindrical cell papilloma originating from the sphenoid sinus, which has been removed by an endoscopic approach.
