The pleura is the most common site of solitary fibrous tumors (SFTs), while such tumors are relatively rare in the head and neck region. This report documents two cases with SFTs developing in the parapharyngeal space. In total, 76 patients with tumors of the parapharyngeal space were operated on under general anesthesia between 2005 and 2012 at the Department of Head and Neck Oncology and Surgery, International University of Health and Welfare. SFT accounted for 2.6% of the cases (2 patients).
The two patients were a 77-year-old man and a 57-year-old woman. Their conditions were diagnosed as SFTs based on postoperative immunohistological test results showing the lesions to be positive for CD34, bcl-2, and vimentin and negative for S-100. Only 11 cases with SFT in the parapharyngeal space have been reported in the literature, to date. Hence, SFT is an extremely rare disease.
