The thyroid is the first endocrine gland to form during embryogenesis. At this stage, incomplete or anomalous migration of thyroid tissue causes ectopic localization of the gland. Submandibular ectopic thyroid tissue with a coexisting normally located thyroid gland is extremely rare. In this case aimed to present the findings of the 65-years-old female patient who is bilateral subtotal thyroidectomy operation performed for multinodular goiter of 12 years ago. Case, painless mass in the right submandibular and infrahyoid region for 6 months was admitted to our clinic with complaints. Result of contrast-enhanced neck computed tomography, ultrasound-guided fine-needle aspiration biopsy and thyroid scintigraphy were found of functional residual thyroid tissue in the normal localization as well as 2×3 cm mass in the submandibular area and 1×2 cm mass lesion in the infrahyoid region. The patient referred to excisional biopsy. Normal thyroid follicules and no evidence of malignancy were found in specimen pathologically. Postoperative follow-up of thyroid function tests were normal.
甲状腺是胚胎发育过程中形成的第一个内分泌腺。在此阶段，甲状腺组织的不完全或异常迁移会导致腺体异位定位。伴有正常位置甲状腺共存的下颌下异位甲状腺组织极为罕见。本文旨在介绍一名65岁女性患者的检查结果，该患者12年前因多结节性甲状腺肿接受了双侧甲状腺次全切除术。病例：一名患者因右下颌下和舌骨下区域无痛性肿块6个月前来我院就诊。颈部增强计算机断层扫描、超声引导下细针穿刺活检和甲状腺闪烁扫描结果显示，正常位置有功能性残余甲状腺组织，下颌下区域有一个2×3厘米的肿块，舌骨下区域有一个1×2厘米的肿块病变。该患者接受了切除活检。病理标本中发现正常甲状腺滤泡，未发现恶性证据。术后甲状腺功能测试的随访结果正常。
