The inductive fibroameloblastoma is a rare odontogenic tumor that occurs in young cats of either sex, predominantly in the anterior maxilla. This article critically reviews the previously published examples with emphasis on microscopic features, relationship to ameloblastic fibroma, and biologic behavior; an additional example is described. This tumor differs microscopically from human ameloblastic fibromas in that it is not well-circumscribed but rather originates multifocally within the supporting connective tissue as characteristic, spherical condensations of fibroblastic connective tissue (ectomesenchyme) associated with islands of odontogenic epithelium. Its biologic behavior requires further study but the tumor apparently is unique to cats and is distinct from human ameloblastic fibroma. Consequently, feline inductive odontogenic tumor is suggested as being a more appropriate designation than inductive fibroameloblastoma.
诱导性纤维成釉细胞瘤是一种罕见的牙源性肿瘤，发生于任何性别的幼猫，主要位于上颌前部。本文对先前发表的病例进行了批判性回顾，重点关注微观特征、与成釉细胞纤维瘤的关系以及生物学行为；并描述了一个额外的病例。该肿瘤在显微镜下与人类成釉细胞纤维瘤不同，其边界不清，而是多灶性起源于支持性结缔组织内，表现为成纤维结缔组织（外间充质）的特征性球形凝聚物，伴有牙源性上皮岛。其生物学行为有待进一步研究，但该肿瘤显然是猫所特有的，且与人类成釉细胞纤维瘤不同。因此，建议将猫诱导性牙源性肿瘤作为比诱导性纤维成釉细胞瘤更合适的命名。
