Ectopic thyroid tissue is a rare developmental abnormality arising from an aberration in the normal migration of the thyroid gland, from the floor of the primitive foregut to its final position. It is usually asymptomatic, often being diagnosed as an incidental finding. However, it can present with symptoms of compression such as chest pain, cough, stridor, dysphagia, dyspnea and superior vena cava syndrome. Herein, we present the case of a 42-year-old male patient, presenting with dyspnea, chest pain and fatigue. Laboratory tests showed low serum levels of thyroid-stimulating hormone (TSH) and a thoracic computed tomography revealed a heterogeneous mass in the anterior mediastinum. The patient underwent a full surgical resection. The postoperative histopathological examination of the mass demonstrated the presence of benign ectopic thyroid tissue with no evidence of malignancy. This case report emphasizes the importance of taking Ectopic thyroid tissue into account when considering the differential diagnosis of a mediastinal mass, as other common diagnoses including lymphomas, dermoid cysts and thymic tumors, require an entirely distinct treatment approach.
异位甲状腺组织是一种罕见的发育异常，由甲状腺从原始前肠底部向其最终位置正常迁移过程中的畸变引起。它通常无症状，常作为偶然发现被诊断出来。然而，它可能会出现压迫症状，如胸痛、咳嗽、喘鸣、吞咽困难、呼吸困难和上腔静脉综合征。在此，我们报告一例42岁男性患者，表现为呼吸困难、胸痛和疲劳。实验室检查显示血清促甲状腺激素（TSH）水平低，胸部计算机断层扫描显示前纵隔有一个不均匀肿块。患者接受了完整的手术切除。肿块的术后组织病理学检查显示存在良性异位甲状腺组织，无恶性证据。本病例报告强调在考虑纵隔肿块的鉴别诊断时，将异位甲状腺组织考虑在内的重要性，因为其他常见诊断，包括淋巴瘤、皮样囊肿和胸腺肿瘤，需要完全不同的治疗方法。
