Abstract

We report an extremely rare case of renal cell carcinoma (RCC) extending into the left atrium through the pulmonary vein next to lung metastasis. The patient was a 76-year-old man. Extirpation of the RCC in the right kidney was carried out. Metastasis to the lungs, mediastinal lymph nodes and the pubis were diagnosed and 4 years later, a myxoma-like tumor was formed in the left atrium by echocardiography. We extirpated of the tumor. During surgery, continuity with the metastatic lesion in the right lung, right inferior pulmonary vein and the left atrium was suggested. Histopathologic examination showed the same histopathology as seen in the RCC.
