Scar site metastasis of renal cell carcinoma diagnosed on-site cytology: A case report

Abstract

Background: Renal cell carcinomas (RCCs) have a propensity for widespread metastases and a wide range of survival rates. They can spread into adjacent organs by direct extension and can invade local or distant sites by lymphatic, hematogenous or lympho-hematogeneous pathways. Scar site metastasis is very rare. Case presentation: We report a rare case of scar site RCC metastasis in a patient who underwent left radical nephrectomy 10 months ago. Conclusion: FNAC is a simple and easy technique that can help in the definitive diagnosis of subcutaneous lesions. A correct early stage diagnosis of metastatic RCC can considerably improve the survival rates.
