Journal Title:Acta Scientific Otolaryngology

The nasal solitary fibrous tumor is an infrequent benign unilateral tumor, were originally first described as a rare mesenchymal neoplasm that commonly involves the pleura, originating from spindle cells, described in 1931 by Klemperer and Rabin. It is further sub-classified as a benign type of mesothelial tumor; it has been reported in other regions such as: the orbit, nasopharynx, thyroid gland, parapharyngeal space, tongue, major salivary glands, lung, mediastinum, extremities, the liver also rarely affect the nasal cavity and paranasal sinus.The diagnosis is primarily histological, it consists in a positive immunohistochemical finding of CD34.Author report a case of 36 years-old man presented with a 3-month history of persistent progressive left nasal bleeding, left nose obstruction and left eye pain is reported. Physical assessment and nasal endoscopy revealed a pain small rubbery mass palpable in the superonasal quadrant of the left eye and the tumor arose from the left ethmoid sinus and extended to the left nasal cavity and the periorbital area. Further imaging by CT and MRI disclosed a large left-sided nasal and periorbital cavity homogeneous mass, occupying left maxillary sinus, left ethmoid, extending to the left frontal sinus and left orbit. The tumor successfully was removed by endoscopy sinus surgery without complication. The tumor had spindle-shaped cells and was positive for CD34, CD99, Bcl-2 and desmin, histopathological analysis of the specimen was consistent with nasal solitary fibrous tumor. This paper describes the presentation, diagnosis, and treatment of a male patient with a Periorbital and Nasal Solitary Fibrous Tumor.
