摘要

腎嗜酸性細胞瘤，早期被認為是一種又腎近側曲小管上皮細胞衛生之腫瘤，後來發現其具有處轉移的惡性特質。術前不易與腎細胞癌區分，但是腎動脈血管攝影有其特殊的特徵，可做為術前診斷的依據。治療原則上必須做根治性的腎切除及主動脈周圍淋巴腺廓清術，除非病人只有單一腎臟或合併有對側腎細胞癌或腎功能不全，才考慮做部份腎切除。台中榮民總醫院報告二位女性病患，她們皆因右上腹疼病接受腹部超音波檢查而發現。在腎動脈血管攝影上，一位表現出典的特徵，另一位則表現出不典型的特徵。兩者皆接受根治性的腎切除及主脈周圍淋巴腺廓清術。分別追蹤8年及3年，未發現有局部復發或遠處轉移。

並列摘要

Renal oncocytoma was previously reported as a benign tumor arising from proximal tubular epithelial cells, but malignant potential with local invasion and distant metastasis has been emphasized in recent literature. It is difficult to differentiate it from renal cell carcinoma, but four typical angiographical signs may give suggestive evidence of the tumor. Radical nephrectomy with lymphadenectomy may be the choice of treatment, except in solitary kidney, bilateral tumors or contralateral renal cell carcinoma. We report two female patients who were found incidentally to have renal tumors during a survey of right upper quadrant pain. Typical angiographic signs were found incidentally to have renal tumors during a survey of right upper quadrant pain. Typical angiographic signs were found in one patient, and atypical signs in the other. Three and eight years after radical nephrectomy with para-aortic lymphadenectomy, there has been no evidence of local recurrence or distant metastasis.
