Enucleation of large meroblastic fibroma: case report

Although ameloblastic fibroma is a benign neoplasm, it has considerable rates of recurrence and malignant transformation into an ameloblastic fibrosarcoma. In this context, we seek to provide important information about the clinical presentation, diagnosis and treatment of this rare and challenging tumor. To this end, we present a case report of a 24-year-old patient with asymptomatic volume increase in the left mandibular region together with a Panoramic X-ray showing a multilocular radiolucent area involving the region of the ramus, angle and mandibular body associated with an impacted element 47. Initial clinical management was complementary exams accompanied by incisional biopsy under AL with anatomopathological result of Ameloblastic Fibroma, treatment of choice was enucleation + peripheral osteotomy of the lesion under AG. He is currently undergoing a one-year follow-up with no evidence of recurrence and healthy new bone formation at the site. Ameloblastic fibroma is a rare benign odontogenic lesion that has a high recurrence rate and potential for malignant transformation. The treatment of choice is enucleation and curettage, and resection with a safety margin may be necessary in cases of larger lesions and recurrences. Long-term follow-up is essential to monitor possible relapses. Therefore, treatment must be individualized, taking into account factors such as age, location, recurrences and postoperative patient morbidity.
