Abstract


A case of solitary fibrous tumor is reported. Solitary fibrous tumor is a rare neoplasia characterized by the proliferation of fusiform cells of mesenchymal origin accounting for at least 2% of all soft tissue tumors. In this present case, the initial diagnosis was salivary gland tumor because of the location in the hard palate. Histologically, the tumor was composed by conjunctive tissue with proliferation of oval and fusiform cells. The immunohistochemical analysis was positive for CD34 and CD99. The lesion was treated by surgical resection. The clinical, imaging, histological and immunohistochemical data are discussed in this study.
