Ameloblastic fibro-odontoma is a rare, benign, and slowly growing neoplasm of the jaw composed of proliferating odontogenic epithelium in ectomesenchymal tissue along with dental hard tissue formation. Herein, we describe a case of an ameloblastic fibro-odontoma in 12-year-old female with paresthesia of the chin and lower lip. Panoramic radiography showed a radio-opacity in the right posterior mandible near the mandibular canal and associated with the right mandibular third molar. Histologically, the lesion contained epithelial and mesenchymal odontogenic components in close proximity to odontoma-like elements. Enucleation and curettage of the affected site in the mandible resulted in resolution of the paresthesia postoperatively.
成釉细胞纤维牙瘤是一种罕见的、良性的、生长缓慢的颌骨肿瘤，由外胚间充质组织中增殖的牙源性上皮以及牙硬组织形成。在此，我们描述一例12岁女性的成釉细胞纤维牙瘤病例，该患者伴有颏部和下唇感觉异常。全景X线片显示右下颌骨后部靠近下颌管处有一不透射线区，与右下颌第三磨牙相关。组织学上，病变包含上皮和间充质牙源性成分，紧邻牙瘤样结构。对下颌骨受累部位进行摘除和刮除术后，感觉异常症状得到缓解。
