摘　　要：成釉细胞纤维牙瘤是一种少见的牙源性肿瘤,多发生于20岁以下,男性多于女性,上下颌骨均可发生,多发生于下颌骨,生长缓慢,无自觉症状,常表现为颌面部的肿胀、牙齿迟萌。X线片常见单房改变,表现为边界清楚的囊性透射影,不易与牙源性肿瘤鉴别。组织学表现,软组织成分为牙源性上皮和胚胎性的结缔组织,类似成釉细胞纤维瘤的形态,硬组织成分为牙本质、釉质样组织,类似牙瘤。恶变可能性低,治疗方式为手术摘除,一般不易复发。该文结合我科收治的成釉细胞纤维牙瘤病例,探讨成釉细胞纤维牙瘤的临床特点及治疗与预后。Ameloblastic fibro-odontoma（ AFO） is a rare odontogenic tumor. It often occurrs at the age under twenty,male more than in female. It is mostly located in the maxilla and mandible,and more common in the mandible. It grows slowly with no symptoms.There is asymptomatic swelling in the maxillofacial region and it delays tooth eruption in the case with AFO. X-ray examination always shows a cystic cavity in the jaw,with clear boundary. It is not easy to be differentiated from odontogenic tumors,such as ameloblastoma and keratocystic odontogenic tumor. Pathological examination shows that neoplasm was composed of proliferating odontogenic epithelium in a cellular ectomesenchymal tissue,similar to ameloblastic fibroma in form. Hard tissue component is similar to odontoma,dental structures resembling dentine and enamel-like tissues. It has a low probability of malignancy. The most common treatment is surgical removal with low potential for recurrence. In this paper,one case with ameloblastic fibro-odontoma was reported and the clinical features and treatment of ameloblastic fibro-odontoma were investigated.
