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。
Objective To investigate the rare pathological features of mature cystic teratoma (MCT). Methods The clinical data of 2 patients with MCT were collected. The ovaries in operation and postoperative biopsy were observed and reviewed. Results 1 case of laparoscopic exploration showed that the size of the ovary and pelvic free body for the smooth surface of porcelain white calcification, mostly microscopic edge of the red staining of collagen fibers without structure, which is the fusion of degenerative fatty tissue , With varying degrees of calcification and ossification; the other case of laparoscopic exploration of ovarian cystic tumor was multilocular, the majority of microscopic thyroid follicular structure, and focal stratified flat epithelium. Conclusion The discussion on the rare clinicopathological features of MCT is helpful to the clinical understanding of the rare form of teratoma.
