Abstract
|
|
|
|
Renal cell carcinoma (RCC) is rare relative to other urological cancers, but relatively common overall among males. Even when primary tumors are successfully removed by surgery, metastases are often noted within a few years. On the other hand, masses found at other sites in patients with RCC may represent different primary cancers. We present the case of a 63-year-old man with a right lung mass and a left lung nodule who underwent radical right nephrectomy for RCC. We found no local recurrence of RCC in the abdomen. Despite treatment for RCC, the right lung mass increased in size. We performed a lung needle biopsy and diagnosed primary lung cancer. Postoperatively, the remaining left lung nodule also increased in size. It was diagnosed as an RCC metastasis upon biopsy and removed by wedge resection. The patient was treated with everolimus after the second surgery.
