Ameloblastic fibro-odontoma (AFO) is a benign, epithelial odontogenic tumor with odontogenic mesenchyme having the histologic characteristics of both ameloblastic fibroma and complex odontoma. This report describes the case of a 14-year-old girl with AFO on the right posterior mandibular region that mimics complex odontoma on incisional biopsy due to the presence of atypical dentin- and cementum-like areas. On histological examination, sections of excisional biopsy showed odontogenic epithelial islands with embryonic connective tissue and decalcified sections showed atypical dentin with dentinal tubules and islands of cementum. These features led to the diagnosis of AFO.
成釉细胞纤维牙瘤（AFO）是一种良性上皮性牙源性肿瘤，伴有牙源性间充质，具有成釉细胞纤维瘤和复合性牙瘤的组织学特征。本报告描述了一名14岁女孩的病例，其右下颌后区患有AFO，在切开活检时因存在非典型牙本质样和牙骨质样区域而酷似复合性牙瘤。组织学检查显示，切除活检切片可见牙源性上皮岛伴胚胎性结缔组织，脱钙切片可见有牙本质小管的非典型牙本质和牙骨质岛。这些特征导致了AFO的诊断。
