Ameloblastic fibro-odontoma (AFO) is a very rare mixed odontogenic tumor (2% of all odontogenic tumors). It is considered as a non-extensive non-aggressive tumor but recurrence and malignant transformation remain possible. We report a voluminous AFO in a child.
A 7-year-old boy presented with a right mandibular and facial swelling. The panoramic radiograph and CT scan revealed a voluminous unilocular radiolucent lesion (10 cm) with an impacted tooth that involved the ramus area and the angle of the right mandible. Enucleation and curettage was performed with a good outcome. There was no recurrence at ten months.
This case is exceptional because of the young patient's age, the large tumor diameter, and the good outcome after ten months. This tumor occurs more often in the posterior region of the mandible and is frequently seen in the first two decades of life. The diagnosis is made on radio-clinical data and may be confirmed by histology. A surgical treatment with complete tumor removal is recommended to prevent recurrence.
成釉细胞纤维牙瘤（AFO）是一种非常罕见的混合性牙源性肿瘤（占所有牙源性肿瘤的2%）。它被认为是一种范围不广泛、侵袭性不强的肿瘤，但仍有可能复发和恶变。我们报告一例儿童巨大AFO病例。
一名7岁男孩出现右下颌及面部肿胀。全景X线片和CT扫描显示一个巨大的单房性透射性病变（10厘米），伴有一颗阻生牙，累及下颌支区域及右下颌角。进行了摘除及刮治术，效果良好。十个月时无复发。
该病例较为特殊，原因在于患者年龄小、肿瘤直径大以及十个月后效果良好。这种肿瘤更常发生于下颌后部区域，常见于生命的前二十年。根据放射学和临床资料进行诊断，可通过组织学确诊。建议进行完整切除肿瘤的手术治疗以预防复发。
