title: [Solitary Fibrous Tumors of the Nasal and Paranasal Sinuses].
abstract: Solitary fibrous tumors (SFT) are uncommon neoplasm that arises in most cases from the pleura. SFT has been rarely observed in the head and neck, but SFT of the paranasal sinuses is especially rare, with 39 previously reported cases to date including those reported in this abstract. Herein we describe three cases of SFT in the paranasal sinuses that were successfully treated endoscopically. Two of the three cases involved patients with no previous history of SFT. The lesion of one of the patients was pathologically diagnosed as SFT preoperatively, but the other was diagnosed as an angiogenic tumor without any biopsies. The tumors were completely resected after arterial embolization by a transnasal endoscopic procedure. The third case involved a 43-year old man, who had undergone medial maxillectomy through a lateral rhinotomy incision to resect SFT four years and seven months before. The tumor relapsed intracranially and, therefore, a craniotomy procedure followed by endoscopic skull base surgery was performed. Radiation therapy was performed postoperatively because the recurrent tumor was pathologically identified as malignant SFT, which had been classified benign at the time of the first resection. All three patients are presently alive with no evidence of disease.
