Obstructive Pneumonitis as a Clinical Presentation of Metastatic Renal Cell Carcinoma 7 Years after Radical Nephrectomy: A Case Report

腎切除術七年後以阻塞性肺炎為臨床表現之轉移性腎細胞癌:一例病例報告

摘要


肺臟為腎細胞癌轉移之好發部位,且為單一轉移之常見病灶。繼發性腎細胞癌轉移仍可發生接受腎臟切除手術後長達數十年之久,故建議終生追蹤檢查。手術切除目前仍為腎細胞癌肺臟轉移之安全且有效的治療方式,且對延長存活亦有所助益。唯術前病患腫瘤風險之評估確認極為重要。我們報告一位66歲於7年前曾患腎細胞並接受腎臟切除手術的男性病患,以阻塞性肺炎為其臨床表現,最後診斷為腎細胞癌肺部轉移向上延伸到truncus intermedius。

並列摘要


The lung is a frequent site of metastasis and often the site of solitary metastasis of renal cell carcinoma (RCC). Since renal cell carcinoma is notorious for metachronous metastasis, even decades after removal of the primary tumor, life-long follow-up has been suggested. Surgical resection for pulmonary metastasis of RCC is a safe and effective treatment that offers improved survival benefits. Preoperative identification of patient and tumor risk factors is imperative in selecting patients for metastasectomy. We report a 66-year-old man who underwent left radical nephrectomy for RCC 7 years before this admission and presented with an obstructive pneumonitis mimicking an endobronchial tumor as metachronous pulmonary metastasis.
