本报告的目的是记录一例意外的成釉细胞瘤侵犯右侧下颌骨桥下区，患者为38岁的柬埔寨女性患者。据称，在此病变之前，有多处放射物透亮，诊断为根尖囊肿，在过去几年中，曾几次对受影响的牙齿进行摘除和牙髓治疗。对部分无牙区进行桥体修复。本病例报告显示了成釉细胞瘤诊断前后的放射学改变。该病例可能是根性囊肿和成釉细胞瘤作为碰撞现象发生的一个例子，或者成釉细胞瘤可能是由于炎症性牙源性上皮囊肿中衬里上皮的肿瘤性转化而发生的。
The purpose of this report is to document a case of unsuspected ameloblastoma involving the right mandibular subpontic region in a 38-year-old Cambodian female patient. This lesion was purportedly preceded by multiple radiolucencies which were diagnosed as radicular cysts and treated a few times in the past years by enucleation followed by endodontic therapy of the affected teeth. Bridgework restoration of the partially edentulous area was performed. This case report demonstrates radiographic changes that occurred in the periods before and after the diagnosis of ameloblastoma. The case may represent an example of radicular cysts and ameloblastoma occurring as a collision phenomenon, or the ameloblastoma may have arisen as a result of neoplastic transformation of the lining epithelium in an inflammatory odontogenic epithelial cyst.
