Heterotopia of thyroid gland can be seen very seldom in humans. Most frequently ectopic thyroid tissue is found in the middle line of neck and chest. Ectopia of thyroid tissue caudal of the diaphragm is an exceptionally rare finding. An explanation results out of the embryology of the thyroid gland development. Reviewing the literature we could find only one case of accessory thyroid tissue in the region of the hepatic porta, it was found at autopsy. In the present case report we describe a 58-year-old woman who had an indistinct tumor in the hepatic porta which was successfully removed. Histologic findings was that of aberrant normal thyroid tissue.
甲状腺异位在人类中极为罕见。最常见的异位甲状腺组织位于颈部和胸部的中线。膈肌尾侧的甲状腺组织异位是一种极其罕见的发现。这可以从甲状腺发育的胚胎学角度得到解释。查阅文献，我们仅发现一例肝门区域副甲状腺组织的病例，该病例是在尸检时发现的。在本病例报告中，我们描述了一名58岁女性，其肝门处有一个边界不清的肿瘤，该肿瘤已成功切除。组织学检查结果为异常的正常甲状腺组织。
