良性囊性畸胎瘤约占所有卵巢肿瘤的10％,其中1.5～2.85％的病例发现其中含小量甲状腺组织(简称甲状组织),常无临床意义。在1～2％的崎胎瘤,甲状组织为其主要成份。该组织一般很少产生过量甲状腺激素而引起甲亢。当有这两个特点之一时即可确定其为卵巢甲状腺瘤(SO)。 据报告,85％的SO发生在绝经前,极少数发生在绝经后。有关SO的确节定义已有较多的报道。开始认为卵巢瘤只由甲状腺组织构成,目前这一概念已有很大改变,所报告的病例仅有20％沿用此标准。有人报告,真正的SO,其甲状组织应远多于
Benign cystic teratoma accounts for about 10% of all ovarian tumors, of which 1.5 to 2.85% of cases found to contain a small amount of thyroid tissue (referred to as thyroid tissue), often without clinical significance. In 1 ~ 2% of the kytoplasm, thyroid tissue is the main component. The organization rarely produce excessive thyroid hormone cause hyperthyroidism. When one of these two characteristics can be identified as ovarian thyroid tumor (SO). It has been reported that 85% of SO occurs in premenopausal women and very few in postmenopausal women. The exact definition of SO has been more reported. The idea that ovarian tumors begin to form only thyroid tissue has changed dramatically and only 20% of reported cases follow this standard. It has been reported that the real SO should have far more thyroid organizations
