Inverting papilloma of the nose and sinuses is a rare, benign neoplasm. Ward first describe a nasal papilloma in 1854, but its infrequent occurerence has delayed accurate understanging. One of the characterstic features was its tendency to recur after removal. A most striking feature of the pathology of the inverting papilloma is a marked proliferation of the epithelial structure which leads to the involvement of the surface with an intact basement membrane. The authors have recently experienced case of huge inverting papilloma which occupied the nasal cavity, maxillary sinus, ethmoid sinus, sphenoid sinus, and frontal sinus. (mass Wt : 200gm) A 49 year old male patient was admitted through the OPD with nasal obstruction, protruded mass in the nasal cavity and left upper eyelid with easy contact bleeding on Fed. 16, 1970.
