Renal cell carcinoma with gallbladder metastasis: a case report

Abstract

Renal cell carcinoma (RCC) is the most frequent renal neoplasm, with a high rate of metastasis, especially in the lungs and bones. The gallbladder is one of the rare metastatic sites. We report an 80-year-old woman who presented with chronic right flank pain for the last six months. A computer tomography scan revealed a heterogeneous right renal mass measuring 86 ×76× 68 mm and multi lithiasis in the gallbladder. A right radical nephrectomy, lymphadenectomy, and cholecystectomy were performed. The postoperative clinical course was uneventful, without any complications. The histological results showed a clear RCC with metastasis to the gallbladder. After 12 - months follow- up, the patient is free from disease. In conclusion, even though the coexistence of metastatic gallbladder from clear RCC is rare, the possibility of concurrence should be considered if suspected findings in the gallbladder are identified intraoperatively.
