Non-small cell lung carcinoma metastatic to the kidney

Abstract

Introduction: Renal metastasis by non-small cell lung cancer is uncommon and usually described at autopsy.

Case presentation: We report the rare case of a 77-year-old man with localized non-small cell lung carcinoma who underwent extirpative surgery and 2 years later presented with gross hematuria and was noted to have a large infiltrating renal mass on computed tomography.

Conclusions: In patients with a prior history of resected localized non-small cell lung carcinoma, presence of a renal lesion should prompt the clinician to consider the possibility of metastasis. Further evaluation should consider this scenario.
