卵巢畸胎瘤204例回顾总结

Summarization and retroversion of 204 cases of ovarian teratoma

目的 进一步了解各类畸胎瘤的临床病理特点 ,进一步提高对本瘤的认识 ,探讨未成熟畸胎瘤的预后及卵巢甲状腺肿的诊断标准。方法 将自 1973～ 1999年间共收治的卵巢畸胎瘤 2 0 4例 ,根据1992年改良世界卫生组织的畸胎瘤分类 ,进行总结 ,回顾。结果 成熟畸胎瘤占 95 .1% ,未成熟畸胎瘤占0 .49% ,成熟畸胎瘤恶变占 0 .98%及卵巢甲状腺肿占 3 .43 %。未成熟畸胎瘤的恶性程度可逆转。卵巢甲状腺肿的诊断标准 ,除肿瘤全部或大部分由甲状腺组织构成 ,或伴有明显甲亢症状外 ,另如有肉眼可识别的甲状腺组织者也可。结论 本文各类畸胎瘤的发生率高低序与资料记载略有不同。对未成熟畸胎瘤患者应积极治疗 ,促使恶性程度逆转 ,提高患者的生存率。各类畸胎瘤具有它独特的形态特点及诊断标准。

Objective To understand well clinical and pathologic features of varied ovarian teratoma.To study prognosis of immature ovarian teratoma and the diagnosis criterion of struma ovarii.To improve our knowledge.Methods During 1973～1999 that of 204 cases of ovarian teratoma treated are summarized retrospectively according to WHO's (1992) classification of ovarian teratoma.Results The incidence of mature teratoma is 95.1%;that of immature teratoma 0.49%;that of mature teratoma malignant change 0.98% and that of struma ovarii 3.43%.Malignant degree of immature teratoma can be reverse.The diagnosis criterion of struma ovarii has one of the following items:the tumor consist completely or mainly of the thyroid tissue;the patients have the symptoms of thyroidism;and the thyriod tissue can be examined by naked eyes in the specimen of mature teratoma.Conclusion The order of varied ovarian teratoma incidences slightly differs that in the from document.The patient of immature feratoma ought to be treated actively,reversal of malignant degree should be promoted and the survival.A variety of ovarian teratoma has a morphologically distinctive and diagnosis criterion.
