A neurofibroma is a type of benign tumor that arises from a nerve bundle consisting of Schwann cells and proliferating fibroblasts. Multiple tumors often occur in cases of neurofibromatosis (von Recklinghausen’s disease), while an isolated tumor is rare. We report the case of a solitary neurofibroma that developed in the mandible of a 76-year-old woman. Transmission radiographic imaging of a mass in the right mandible seen on panoramic radiography performed as part of a regular medical checkup led the patient to be referred to our hospital. Biopsy findings resulted in a diagnosis of neurofibroma. A surgical procedure was performed, during which the tumor and inferior alveolar nerve vascular bundle were found to be partially in contact, although complete separation was possible. Presently, approximately 5 years after the operation, no recurrence has occurred.
