We report a rare case with a solitary fibrous tumor of the cheek. A 73-year-old male with cheek swelling referred to our hospital. At the initial visit, a movable tumor measuring 20 × 15 mm was palpable. Therefore, the patient underwent excisional biopsy of the tumor under general anesthesia. Immunohistochemical staining showed the tumor cells to be positive for CD34, without organization of spindle cells into any discernible pattern, leading to a diagnosis of solitary fibrous tumor. The patient is now being carefully followed. There has been neither recurrence nor metastasis for 6 years, to date.
