Solitary fibrous tumor (SFT) is a fibrous mesenchymal tumor that was first reported on the pleura by Lietaud in 1767, followed by Wagner in 1870 and Klemperer and Rabin in 1931. SFT is rare in the oral cavity, and some studies reported that SFT can arise in the buccal region and tongue. However, there is only one report of SFT arising in the soft palate in Japan. The patient was an 82-year-old woman with 20 × 10 mm and 8 × 8 mm elastic masses on the right side of the soft palate. MRI revealed two well-circumscribed masses on T1-weighted images, which had the same intensity level as the muscle, and on T2-weighted images, which had uneven high signal intensity. Because a biopsy specimen was diagnosed as SFT, we performed tumor resection with the patient under general anesthesia. The patient had no signs of recurrence or metastasis as of 1 after surgery, and is still under follow-up.
