造釉细胞纤维牙瘤是一种良性混合性牙源性肿瘤。早年的文献曾将造釉细胞纤维牙瘤与造釉细胞牙瘤相混淆。1967年Hooker将两者明确分开,1981年Stootweg进一步认为造釉细胞纤维牙瘤是一种良性的混合性牙瘤,属错构瘤性病变。这种肿瘤约占牙源性肿瘤的2％。 1.病例介绍:牛某,男性,42岁,住院号34247。颏部隆起七个月。七个月前患者被动物踢伤颏部,当时牙龈少许出血,几天后颏部稍隆起,日渐增大,无任何不适,未治疗。近日因包块增长明显,致面部不对称即到我院求治。门诊以“颏部造釉细胞瘤”收入院。入院后检查:患者一般情况尚好,面部不对称, Ameloblastoma is a benign mixed odontogenic tumor.
