Previously published cases of ameloblastoma in the horse are reviewed in detail for their acceptability as examples of that tumor; an additional one is described. So far, this rare equine lesion has been shown to have two histologic patterns. The first consists of islands and sheets of epithelium that exhibit the basal cell characteristics of ameloblastoma; the central cells comprise stellate reticulum. The second exhibits these basal cell features less markedly and the central cells are spindle-shaped and closely packed. The biologic behavior of the equine ameloblastoma is thought to be the same as in human beings, a slowly growing, invasive lesion that does not metastasize. However, this conclusion requires confirmation.
对先前发表的马成釉细胞瘤病例进行了详细回顾，以评估其作为该肿瘤实例的可接受性；并描述了另外一例。到目前为止，这种罕见的马病变已显示出两种组织学模式。第一种由呈岛屿状和片状的上皮组成，表现出成釉细胞瘤的基底细胞特征；中央细胞构成星网状层。第二种模式中，这些基底细胞特征不太明显，中央细胞呈纺锤形且排列紧密。马成釉细胞瘤的生物学行为被认为与人类相同，是一种生长缓慢、具有侵袭性且不发生转移的病变。然而，这一结论需要证实。
