一例甲状腺功能正常的20岁白人妇女,出现两个可触及的甲状腺结节。闪烁扫描显示峡部与一可触及的结节相应的位置有一吸收增加区。其余甲状腺,包括位于左叶上部的可触及的另一结节,吸收减少。显微镜检查显示弥漫性淋巴性甲状腺炎,峡部滤泡性腺瘤和左上叶粘液表皮样癌。已证实甲状腺以外无粘液表皮样癌的原发灶。甲状腺粘液表皮样癌以前未曾报导,简要地复习了文献并讨论了病因。
A 20-year-old white woman with normal thyroid function developed two palpable thyroid nodules. The scintigraphic scan shows an area of increased absorption at the site of the isthmus corresponding to a palpable nodule. The remaining thyroid gland, including another palpable nodule located in the upper part of the left lobe, had reduced absorption. Microscopic examination revealed diffuse lymphoid thyroiditis, follicular follicular adenoma, and mucous epidermoid carcinoma in the left upper lobe. It has been confirmed that there is no primary lesion of mucoepidermoid carcinoma other than the thyroid gland. Thyroid mucoepidermoid carcinoma has not previously been reported, a brief review of the literature and discussion of the cause.
