摘要

下頜部之異位甲狀腺在臨床上是非常少見的，而合併有正常位置之甲狀腺者更罕見。本病例為61歲女性，6年前因左甲狀腺節結接受甲狀腺左葉部份切除術。兩年前在右下頷區發現一個大小約3×3 cm之腫瘤，細針穿刺並無異狀發現，腫瘤切除病理報告為甲狀腺節結。由於70%以上之異位甲狀腺缺乏正常位置之甲狀腺，若貿然切除可能會造成終身甲狀腺機能低下。所以雖然下頜部之異位甲狀腺很罕見，但我們在臨床上對於頜部之腫瘤，仍須將異位甲狀腺列入鑑別診斷，以防止醫原性甲狀腺機能低下之發生。

Ectopic thyroid tissue located in the submandibular region was rather rare and that with a coexisting normal locate thyroid gland had been reported in only two papers. In March 2000, we had a patient who suffered from right submandibular mass for two years. She ever received thyroid surgery for nodular goiter of left lobe of thyroid 6 years ago at other hospital.
