Ameloblastic fibroma (AF) is a rare benign odontogenic tumor that usually occurs in the first two decades of life. It can occur in the mandible or maxilla but is most commonly found in the posterior region of the mandible. A 6-year-old female patient applied to our clinic due to swelling in her mouth. The patient had no medical history of previous trauma or pain in the affected area. Enucleation of the tumor was performed under general anesthesia. Following enucleation, surrounding bone curettage was performed and adjacent teeth were removed. As a result of morphological and immunohistochemical examinations, the patient was diagnosed with ameloblastic fibroma. Although AF is a rare tumor, it is more common in children. Patients with AF need to be followed for a long time due to the ability of AF to turn into ameloblastic fibrosarcoma, which is its malignant form. The patient is followed frequently and has been asymptomatic for 1 year.
