Ectopic thyroid tissue in the submandibular region is exceptionally rare. Nevertheless, the treating physician should consider this condition within the differential diagnosis of a submandibular mass.
Case report of ectopic thyroid tissue presenting as a submandibular mass in a patient with hyperthyroidism, together with a review of the English-literature concerning ectopic thyroid tissue.
To our knowledge, this is the first report of ectopic thyroid tissue presenting as a submandibular mass and causing hyperthyroidism. Removal of the submandibular mass resulted in normalisation of thyroid function, and subsequent reduction in the patient's antithyroid medication dosage. Ectopic thyroid tissue should be suspected in any patient with a submandibular mass. Prior to resection of such a lesion, it is essential to ensure that normal, functioning thyroid tissue is present elsewhere. Ectopic thyroid tissue can also present with pathology similar to that affecting the normal thyroid gland.
下颌下区异位甲状腺组织极为罕见。然而，治疗医生在鉴别诊断下颌下肿物时应考虑到这种情况。
报告1例表现为下颌下肿物的异位甲状腺组织合并甲状腺功能亢进患者的病例，并复习有关异位甲状腺组织的英文文献。
据我们所知，这是首例表现为下颌下肿物并导致甲状腺功能亢进的异位甲状腺组织的报告。切除下颌下肿物后甲状腺功能恢复正常，患者随后的抗甲状腺药物剂量减少。任何下颌下肿物患者均应怀疑有异位甲状腺组织。在切除此类病变之前，必须确保其他部位存在正常的、有功能的甲状腺组织。异位甲状腺组织也可出现与影响正常甲状腺的病变相似的病理表现。
