Primary Tracheal Squamous Cell Carcinoma-Presenting with Circumferential Invasion and Treated with Photodynamic Therapy

原發性氣管內鱗狀細胞癌-以氣管環狀侵犯為表現並接受光動力療法治療

摘要


原發性的氣管腫瘤非常罕見,其診斷往往需要倚賴電腦斷層掃瞄。本篇病例報告一位50歲女性病患,主訴慢性咳嗽約一年。胸部X光及電腦斷層皆無發現異常。支氣管鏡檢查發現瀰漫性且呈環狀侵犯的氣管內乳突瘤狀病灶,而支氣管鏡超音波檢查發現此病灶已侵犯超越基底膜的範圍。該病灶的病理切片結果為鱗狀細胞癌。病患接受光動力療法做為第一線治療且初步獲得不錯的腫瘤治療反應。

並列摘要


Primary neoplasms of the trachea are extremely rare. The diagnosis usually depends on computed tomography (CT) scan. We report a 50-year-old woman who suffered from chronic productive cough for 1 year. Roentgenograms and chest CT showed no abnormal finding. Bronchoscopy showed diffuse circumferential papilloma-like lesions at the trachea. Endobronchial ultrasound showed submucosal invasion of the trachea. The pathology of the endotracheal biopsy showed squamous cell carcinoma. She received photodynamic therapy as first-line treatment with a good response and tumor regression.
