Pediatric Solitary Fibrous Tumor of the Sublingual Gland with Malignant Potential

Solitary fibrous tumor(SFT) is an unusual primary mesenchymal spindle cell tumors, most commonly arising in the pleura. Although the majority of these tumors exhibit benign behavior and have a good prognosis, but minority of patients with these tumors are at risk for local recurrence and distant metastaseis. Recently, we experienced a rare case of 12-years-old pediatric SFT patient arising in the sublingual gland, which shows histopathologically malignant potential. So we report this case with a review of literatures. (J Clinical Otolaryngol 2018;29:114-118)
