Abstract：
Calcifying odontogenic cyst (COC) was first described and classified by Gorlin et al. It is defined as a cystic lesion in which the epithelial lining shows a well defined basal layer of columnar cells, an overlying layer that often resemble stellate reticulum and masses of ghost cells that may be in the epithelial cystic lining or in the fibrous capsule. The lesion generally occurs in the region anterior to maxillary and mandibular molars and either intraosseous or extraosseus. This entity might present as a cystic or solid lesion. Praetorius et al. classified COC into 2 main entities namely a cyst (Type 1) and a neoplasm (Type 2). The present case report exhibit a cystic lesion with both luminal and mural component.
摘要：
Gorlin等人首先对钙化性牙源性囊肿（COC）进行了描述和分类。它被定义为囊性病变，其中上皮衬里显示出明确的柱状细胞基底层，通常类似于星状网状结构的覆盖层和可能在上皮囊性衬里或纤维囊中的幽灵细胞团。病变通常发生在上颌和下颌磨牙以及骨内或骨外的区域。该实体可能表现为囊性或实性病变。Praetorius等人。COC分为2个主要实体，即囊肿（1型）和肿瘤（2型）。本病例报告显示囊性病变，具有腔和壁成分。
