牙源性钙化囊肿是一种少见的肿瘤,自Gort~in首先作为一种独立的病损报道和命名以来,至今国内外已有不少报道。Praetorius将此病损分为单囊型和肿瘤型两种类型。这一分类被Shafer采用。现将我院受检的10例牙源性钙化囊肿报告如下,并结合文献就此囊肿的分型及生物学行为等进行讨论。材料及方法材料为我院1973年11月～1987年2月经检的病例。全部标本用10％福尔马林固定,石蜡包埋、切片,H.E染色。根据Praetorius的分型方法归类,光镜观察。结果一、临床资料:见附表 Odontogenic calcified cysts are rare tumors. Since Gortin was first reported and named as an independent lesion, so far there have been many reports both at home and abroad. Praetorius will be divided into single lesions and tumor type of two types. This classification is used by Shafer. Now in our hospital examined 10 cases of odontogenic calcified cysts are reported below, and in conjunction with the literature on this cyst classification and biological behavior are discussed. Materials and Methods Materials for our hospital from November 1973 to February 1987 through the seizure of cases. All specimens were fixed with 10% formalin, embedded in paraffin, sliced ​​and stained with H.E. Classification according to Praetorius's classification method, light microscopy. First, the clinical data: See Schedule
