title: Solitary fibrous tumor arising from the superior nasal turbinate: a case report.
abstract: Solitary fibrous tumor is a rare neoplasm, which was first described as a primary spindle-cell tumor of the pleura, is a type of mesenchymal tumor. Although the majority of these tumors originate in the pleura, they can also derive from extrapleural sites, such as the liver, lung, abdomen, and extremities. We report a rare case of a nasal solitary fibrous tumor that originated from the nasal superior turbinate. The tumor, measuring 45 × 25 × 10 mm, was in the right nasal cavity. We successfully removed the tumor in one piece through endonasal endoscopic surgery. The tumor had spindle-shaped cells within a collagenous stroma and was positive for CD34. There has been no evidence of tumor recurrence in the 14 months following surgery.
