摘要
Gouty tophi are rarely encountered by otolaryngologists, especially in prelaryngeal or laryngeal forms. A 59-year-old man presented with a history of gouty arthritis and hyperuricemia, having found a painless anterior midline neck mass. A CT scan showed a hyperdense trans-thyroid cartilage mass with endolaryngeal extension. We excised the trans-thyroid cartilage mass through an anterior neck incision without entering the laryngeal box. Histopathologic examination revealed abundant uric acid deposits with multinucleated foreign body giant cells and chronic inflammatory cells, compatible with typical gouty tophus. Postoperative course was uneventful and without recurrence. We also reviewed relevant literature regarding the diagnosis and treatment of laryngeal tophi.

痛風石在頭頸很少見，尤其是在喉部或喉前，文獻回顧喉部痛風石到目前爲止少於20例。報告1名59歲男性有高尿酸血症及痛風關節炎病史，主訴前頸腫塊數月，局部無感染或發炎徵象。電腦斷層掃描顯示一疑似鈣化腫塊從甲狀軟骨長出並往喉内延伸。手術切除於2017年5月進行，由前頸進入將此經甲狀軟骨腫塊切除並保留内喉黏膜。病理報告顯示許多尿酸結晶，慢性發炎細胞及異物巨細胞，爲典型痛風石診斷。術後傷口復原良好，門診追蹤至今無復發跡象。喉部痛風石相當罕見，因此我們回顧了診斷及治療相關的文獻。
