Solitary fibrous tumor (SFT) was first reported in 1931 by Klemperer and Rabin 1). Although this tumor occurs mostly in the pleura, extra-pleural SFT including the head and neck region has also been reported. This paper describes a case of SFT arising in the lower gingiva. A 49-year-old woman visited our clinic because of swelling of the lower gingiva. Intra-oral examination revealed a well-defined elastic hard mass measuring 50 × 33 × 25 mm in the anterior lower gingiva. After several clinical and radiographic examinations, a clinical diagnosis of a benign tumor in the lower gingiva was made. The lesion was surgically excised with the patient under general anesthesia. The histological diagnosis was SFT. Two years and 10 months after surgery, no recurrence was observed. This article includes a review of previously reported cases.
