Carcinoma of the sphenoid sinus is rare, and even tumors found in the sphenoid sinus are mostly those tumors invading from the epipharynx or the nasal sinuses. Primary carcinoma case of this sinus has not been reported in the literature.In this paper we present a case of primary cancer of the sphenoid sinus. The patient was a 53-year-old male, whose main complaints were headache, amaurosis, exophthalmos and motor disturbance or the left eye without any nasal symptoms. A small polypoid tumor was found in the olfactory fissure on anterior rhinoscopy and not on posterior rhinoscopy.After dissection of the maxilla it was revealed that this tumor has originated and extended from the lateral wall of the sphenoid sinus which was destructed exposing the overlying dura mater. The sinus cavity was filled with papillomatons tumor, but the median wall was covered by thin and flat layer-which was later proved as proliferated squamous cell epithelium, and the rest was covered by the ciliated epithelium.The ethmoid ahd maxillary sinuses seemed intact and infiltration of the tumor was not confirmed histologically in their mucous membrane.The authors believed that this case could be the first case of primary cancer of the sphenoid sinus ever reported in the medical literature.
