Abstract
- Solitary fibrous tumor (SFT) is a rare mesenchymal neoplasm first described and often encountered in the pleura. It has also been documented in a variety of extrapleural sites including the abdominal cavity, respiratory tract, lung, breast, and rarely in the head and neck region. SFT in the hard palate is an extremely unusual location. We present a rare case of SFT that presented as a palate mass, which was suggested as a mesenchymal cell neoplasm by preoperative punch biopsy, and finally diagnosed as STF after successful surgical excision. SFTs should be considered as a differential diagnosis of palate benign tumor when preoperative pathologic findings show mesenchymal neoplasms of fibroblastic or myofibroblastic origin. Possible malignant variants should be distinguished by evaluating the histological parameters, including high cellularity, frequent mitotic activity, nuclear pleomorphism, and presence of necrosis.
