Benefit of a Second Opinion for Lung Cancer: No Metastasis to the Kidney but a Synchronous Primary Renal Neoplasm

BACKGROUND: The finding of a renal mass on imaging is suggestive of metastatic non-small cell lung cancer in the presence of a lung tumor but can also have another origin. CASE REPORT: We describe the case of a patient diagnosed with stage IV lung cancer based on a renal metastasis. A second opinion...

Sumario:BACKGROUND: The finding of a renal mass on imaging is suggestive of metastatic non-small cell lung cancer in the presence of a lung tumor but can also have another origin. CASE REPORT: We describe the case of a patient diagnosed with stage IV lung cancer based on a renal metastasis. A second opinion including review of histopathological data and additional imaging followed by lung surgery and cryoablation of the kidney lesion revealed two tumors of different origins, non-small cell lung cancer and a renal cell carcinoma. DISCUSSION: The presence of a renal mass diagnosed on a CT scan in a patient with lung cancer is not always synonymous with metastatic disease. Confirmation of diagnosis by tissue sampling is mandatory, especially if a synchronous primary tumor is possible.
