乳癌切除術後32年目に肺・リンパ節転移・胸膜播種をきたした1例

Lung, Lymph Nodes and Pleural Metastasis of Breast Cancer Developed Thirty-two Years after Radical Mastectomy：Report of a Case

はじめに　乳癌切除術後長期間経過後に晩期再発を認めることがあるが，30年以上を経て再発する症例はまれである．われわれは，乳癌切除術後32年目に肺・多発リンパ節転移と胸膜播種を認めた症例を経験したので，文献的考察を加えて報告する．

We report a case of distant metastases developed 32 years after radical mastectomy for right breast cancer. A 70s-year-old women visited the local hospital because of productive cough. Chest computed tomography （CT） showed a 10 mm nodule in the right middle lobe, multiple lymph nodes swelling and small pleural nodules. Surgical biopsy of lung and pleural tumor provides the pathological diagnosis of solid-tubular carcinoma expressing estrogen receptor and progesterone receptor, suggesting metastatic lesions of breast cancer.
