Abstract |
Non small cell lung cancer (NSCLC) frequently metastasizes to brain, bone, liver, and adrenal glands. While an autopsy of NSCLC reveals some cases of metastasis to the kidney, clinical detection of renal metastases is extremely rare. Furthermore, metastases to the kidney usually present as multifocal or bilateral lesions and solitary renal metastases are usually suspected to be renal cell carcinoma. We now report a case of asymptomatic solitary renal metastasis from a primary squamous cell carcinoma, which was detected by routine surveillance with abdominal CT after curative surgery. |
