title: [Single fibrous tumor of the parapharyngeal space].
abstract: A solitary fibrous tumor (SFT) of the parapharyngeal space presented with local symptoms (hearing loss, nasal obstruction, and paralysis of the soft palate and tongue). SFT, originally described as a mesothelial tumor of the pleura, now is recognized as a mesenchymal tumor that occurs in different locations. In the head and neck region, about 50 cases have been reported. This is the fifth published report of an SFT of the parapharyngeal space. The diagnosis was confirmed by immunohistochemical (positivity for vimentin, CD34, and CD99) and ultrastructural markers (fibroblastic characteristics).
