摘　　要：目的探讨成熟性囊性畸胎瘤(MCT)的罕见病理学特征。方法收集2例MCT患者的临床资料,对术中冷冻及术后活检的卵巢进行病理学观察分析并复习相关文献。结果 1例腹腔镜探查显示,大小不等的卵巢及盆腔游离体,为表面光滑的瓷白色钙化体,镜下边缘多为红染无结构的胶原化纤维,其内为融合退变的脂肪组织,伴不同程度的钙化及骨化;另1例腹腔镜探查显示卵巢囊性肿物为多房性,镜下可见大部分为甲状腺滤泡结构,及局灶复层扁平上皮。结论对MCT的罕见临床病理学特征的探讨,有助于临床对畸胎瘤罕见形态的认识。Purpose To investigate the rare pathological characteristics of mature cystic teratomas（ MCT）. Methods The two patients underwent laparoscopy for an enlarged ovary mass for histological examinations during and after operation. Results Laparoscopy of the first patient showed varying sizes of loose nodes from the ovary and pelvic surface,which were smoothly porcelain white calcified bodies. Microscopically,the edge of the dodies was red dyed and structureless collagenized substances,in which there were degraded adipose tissues with varying degrees of calcification and ossification. Laparoscopy of the second patient showed a multilocular ovarian cystic mass,which was composed of thyroid follicular structure and stratified squamous epithelium, microscopically. Conclusions The rare pathological characteristics of MCT provide important clues to the diagnosis as well as differential diagnosis.
