肺癌術後に発生した限局性結節性肺アミロイドーシスの1例

Localized Nodular Pulmonary Amyloidosis after Resection of Lung Cancer；Report of a Case

限局性結節性肺アミロイドーシスはまれな疾患で，画像所見からは良悪性の鑑別はむずかしく，確定診断のために外科的生検が必要となることが多い．われわれは，肺癌術後に出現した肺結節に対し胸腔鏡下手術を施行し確定診断にいたった限局性結節性肺アミロイドーシスを経験したので，若干の考察を加えて報告する．

A 79-year-old man had undergone endoscopic colorectal resection for colon cancer and partial resection of right S2 for lung cancer in 2007. Two years later, enlargement of a small nodule in the right S10 detected by chest computed tomography was noted. Partial lung resection was performed in April 2009, and the pathological diagnosis was localized nodular pulmonary amyloidosis.
