腎癌術後肺転移が疑われた肺過誤腫の3例

Abstract

症例1(63歳男性).人間ドックにて右腎腫瘤を指摘された.症例2(77歳男性).胆石精査中の超音波検査にて左腎腫瘤を指摘された.症例3(61歳女性).肺炎精査中の超音波検査にて右腎腫瘤を指摘された.いずれの症例も腎癌の臨床診断で腎摘除術を施行したところ, 術後9ヵ月～1年に肺転移を疑わせる腫瘤が出現した.肺部分切除術を行った結果, いずれの症例も病理診断は肺過誤腫であった

We report 3 patients with pulmonary hamartoma, all of whom had undergone nephrectomy for renal cell carcinoma. A lung tumor was detected 2 to 9-months following nephrectomy. Preoperative diagnosis was pulmonary metastasis from renal cell carcinoma and pulmonary tumor resection was performed in each case. There was a 9- to 12-month interval between the detection and resection of the lung tumor. The histological diagnosis of the lung tumor in all three patient was pulmonary hamartoma. Following the resection of the lung tumor, recurrence was not noted in any of the patients.
