Abstract
A spontaneous ameloblastic fibro-odontoma is described in a 73-wk-old female mouse. The tumor was located in the molar mandibular region. The diagnosis was made on the basis of the histologic presence of odontogenic epithelial tissue embedded in mesodermal tissue resembling dental papilla, and containing in addition dentin and enamel. The positive reaction for keratin and vimentin confirmed the presence of ectodermal and mesodermal elements respectively in the tumor.
摘要
一只73周龄雌性小鼠身上发现了一例自发性成釉细胞纤维牙瘤。肿瘤位于下颌磨牙区。诊断依据是组织学检查发现牙源性上皮组织嵌入类似牙乳头的中胚层组织中，且还含有牙本质和牙釉质。角蛋白和波形蛋白的阳性反应分别证实了肿瘤中存在外胚层和中胚层成分。
