Abstract

A cyst is defined as a pathological cavity which may or may not have an epithelial lining and which has a fluid, semi-fluid, or gaseous contents and is not formed by the accumulation of pus. The calcifying epithelial odontogenic cyst (CEOC) was first reported by Gorlin et al. in 1962. At that time, it was classified as a cyst related to the odontogenic apparatus. It was later renamed as calcifying cystic odontogenic tumor (CCOT) in the World Health Organization classification devised in 2005 due to its histological complexity, morphological diversity, and aggressive proliferation. CCOT was later recognized by numerous names including Gorlin cyst, calcifying ghost cell odontogenic cyst and/or dentogenic ghost cell tumor. It has a peak incidence during the second and third decades of life and does not demonstrate any gender predilection. Radiographically, CEOC may appear as a unilocular or multilocular radiolucent lesion with either well-circumscribed or poorly-defined margins and may also be observed in association with unerupted teeth. Calcification is an important radiographic feature for the interpretation of CEOC/CCOT. The typical histopathological features of CEOC include a fibrous wall and lining of the odontogenic epithelium with either columnar or cuboidal basal cells resembling ameloblasts. The treatment of choice for CEOC is conservative surgical enucleation; however, recurrence is also not found to be uncommon. Herein, we are reporting a case of the same in a 21-year-old female which was a great dilemma during the diagnostic workup.

摘要

囊肿被定义为一个病理性腔隙,它可能有也可能没有上皮衬里,其内容物为液体、半液体或气体,且不是由脓液积聚形成的。钙化上皮性牙源性囊肿(CEOC)于1962年由戈林等人首次报道。当时,它被归类为与牙源性器官相关的囊肿。由于其组织学复杂性、形态多样性和侵袭性增殖,在2005年世界卫生组织的分类中,它后来被重新命名为钙化囊性牙源性肿瘤(CCOT)。CCOT后来有许多名称,包括戈林囊肿、钙化幽灵细胞牙源性囊肿和/或牙源性幽灵细胞瘤。它在生命的第二个和第三个十年发病率最高,没有任何性别倾向。在影像学上,CEOC可能表现为单房或多房的透射性病变,边缘清晰或不清晰,也可能与未萌出的牙齿有关。钙化是解释CEOC/CCOT的一个重要影像学特征。CEOC的典型组织病理学特征包括纤维壁和牙源性上皮衬里,其基底细胞为柱状或立方状,类似于成釉细胞。CEOC的首选治疗方法是保守性手术摘除;然而,复发也并不少见。在此,我们报告一例21岁女性的该病例,在诊断检查过程中这是一个很大的难题。
