Abstract

Ameloblastic fibro-odontoma (AFO) is a benign odontogentic tumor without an aggressive behavior, unlike the similar ameloblastic fibroma. A 9-year-old boy, with tooth eruption failure, underwent enucleation and curettage of a well-defined variable radiolucent and radio-opaque right mandible lesion. There was odontogenic epithelium with peripheral palisading in a loose myxoid stroma as well as a disorganized component of dentin, enamel, and cementum, features of an AFO. AFO is an odontogenic mixed tumor of epithelium and mesenchyme.

摘要

成釉细胞纤维牙瘤（AFO）是一种良性牙源性肿瘤，与相似的成釉细胞纤维瘤不同，它没有侵袭性。一名9岁男孩因牙齿萌出失败，接受了对右侧下颌骨边界清晰、透射线与阻射线相间的病变进行的摘除和刮治术。在疏松的黏液样基质中存在具有外周栅栏状排列的牙源性上皮，以及牙本质、釉质和牙骨质的杂乱成分，这些都是成釉细胞纤维牙瘤的特征。成釉细胞纤维牙瘤是一种上皮和间充质的牙源性混合肿瘤。
