The so-called calcifying odontogenic cyst (COC) shows extensive diversity in its clinico-histopathological appearances and biological behaviour. Because of this diversity, there has been confusion and disagreement on the terminology and classification of this lesion. The attempts at classification of COC may be divided into two concepts. The first concept is the "monistic" one that all COCs are neoplastic in nature, even though the majority are cystic in architecture and appear to be non-neoplastic. The second is the "dualistic" concept that COC contains two entities: a cyst and a neoplasm. Although the World Health Organization (WHO) classified COC as an odontogenic tumour in 1992 based on the former concept, current thinking favors strongly the latter one. In this article, several previous classifications of COC in the literature are discussed and a new simple classification scheme based on the "dualistic" concept is proposed.
所谓的牙源性钙化囊肿（COC）在临床组织病理学表现和生物学行为上具有广泛的多样性。由于这种多样性，关于该病变的术语和分类一直存在混淆和分歧。对COC进行分类的尝试可分为两种概念。第一个概念是“一元论”，即所有COC本质上都是肿瘤性的，尽管大多数在结构上是囊性的，且看似非肿瘤性。第二个是“二元论”概念，即COC包含两种实体：囊肿和肿瘤。尽管世界卫生组织（WHO）在1992年基于前一种概念将COC归类为牙源性肿瘤，但目前的观点强烈倾向于后一种概念。在本文中，讨论了文献中先前对COC的几种分类，并提出了一种基于“二元论”概念的新的简单分类方案。
