精品牙源性钙化囊肿课件

牙源性钙化囊肿 Calcifying Odontogenic Cyst COC 牙源性钙化囊肿 牙源性钙化囊肿是一种特殊的牙源性 病损。占牙源性肿瘤的3.35。1962年R. J. Gorlin 、R. A. Vickers、H. O. Sedano 等首先报告此病，并称之为“牙源性（角 化）钙化上皮囊肿”。病变具有囊肿的特 点，同时又具有实性肿瘤的许多特点。 Dr. Robert J. Gorlin Dr. Robert A. Vickers Dr. Heddie O. Sedano Calcifying odontogenic cyst 1981年Praetorius等对本病进行了 详细的研究，对本病的临床和病理特 征有了更好的认识。所谓牙源性钙化 囊肿实际上是两个实体，一个是囊肿 ，一个是肿瘤。 Calcifying odontogenic cyst 病理学可以分为三种类型： 囊性型 (cystic lesion) 牙源性影细胞瘤 (odontogenic ghost cell tumor) 牙源性影细胞癌 (odontogenic ghost cell cacinoma) Calcifying odontogenic cyst 1.囊性型（cystic lesion) 发生于任何年龄，青壮年多见。 75发生于颌骨内，25发生于颌骨外 ，表现为龈组织肿胀。 Calcifying odontogenic cyst X 线片表现为界限 清楚的放射透光区， 腔内含大小不等的钙 化物质。 Calcifying odontogenic cyst l镜下：囊壁衬有复层鳞状上皮，基底膜境 界清晰且着色明显。基底细胞呈柱状或立方状 ，柱状细胞的胞核远离基底膜，染色深，胞浆 内可见空泡。在基底层有时可见黑色素。基底 层上方有数层排列疏松的细胞，似星网状层。 在此层内可见特征性的角化的影上皮细胞（ ghost epithelial cell），呈不规则堆积。影细 胞呈淡伊红色，细胞界限清楚，核消失而不着 色，在胞核的部位出现阴影。影细胞常发生钙 化。 l上皮基底层下方可见带状发育不良牙本质 。有些病例中见有广泛牙硬组织形成，类似于 牙瘤。 Calcifying odontogenic cyst Calcifying odontogenic cyst Calcifying odontogenic cyst Calcifying odontogenic cyst l组织来源：囊性型牙源性钙化囊肿 为单囊性病损，一般认为来源于缩余釉 上皮或来源于牙滤泡、龈组织或颌骨内 的牙源性上皮剩余。 l囊壁内的类牙本质或牙瘤成份乃是 上皮诱导产生的。 l生物学特性：良性病损，有完整包 膜，术后不复发。 Calcifying odontogenic cyst 2.牙源性影细胞瘤 (odontogenic ghost cell tumor) 病变主要发生于老年人，病变可位 于颌骨内或颌骨外。 镜 下：由成釉细胞瘤样牙源性上皮构 成并伴有影细胞形成和少量类牙本质。牙源性 上皮呈条索或岛状浸入正常结缔组织。类牙本 质与牙源性上皮直接相邻。有时也可伴有成釉 细胞纤维瘤或牙源性腺样瘤病变。 Praetorius等主张本病为一独立的肿瘤， 称为牙本质生成性影细胞瘤（Dentinogenic ghost cell tumor）。 肿瘤呈浸润性生长，手术后易复发。 Calcifying odontogenic cyst Calcifying odontogenic cyst 3.牙源性影细胞癌 (odontogenic ghost cell carcinoma) 肿瘤内既有牙源性钙化囊肿的特 征，包括多少不等的影细胞，又有恶性 细胞特点和浸润性生长。 术后复发率高。
