Renal cell carcinoma in a lumbar ectopic kidney

INTRODUCTION: Lumbar ectopic kidney is a rare developmental renal anomaly. We report a case of renal cell carcinoma in lumbar ectopic kidney with an abnormality of the main renal artery piercing the renal parenchyma.

Sumario:INTRODUCTION: Lumbar ectopic kidney is a rare developmental renal anomaly. We report a case of renal cell carcinoma in lumbar ectopic kidney with an abnormality of the main renal artery piercing the renal parenchyma. CASE PRESENTATION: A 70‐year‐old female was referred to our division with an incidentally diagnosed ectopic kidney. Computed tomography angiography detected the right kidney at the lumbar (L3‐L4) level with an early‐enhanced 44‐mm‐diameter mass. The kidney had a laterally facing renal hilum and renal arteries piercing the renal parenchyma from the medial side. An open radical nephrectomy was performed using a peritoneal approach, and no perioperative complications were observed. The pathological diagnosis was clear cell carcinoma (pT1). CONCLUSION: This is the first case report of renal cell carcinoma in a lumbar ectopic kidney. It highlights the importance of preoperational imaging for aberrant artery and careful surgical management.
