Abstract
Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is an alternative approach to sample kidney lesions that is less commonly used compared to percutaneous CT or ultrasound guidance. In this case, we present a 70-year-old female who was diagnosed with metastatic renal cell carcinoma (RCC) 18 years post-nephrectomy with EUS-FNA in conjunction with immunohistochemistry. This case report supports the use of EUS-FNA in conjunction with immunohistochemistry as a robust technique that can safely and effectively diagnose recurrent renal cell carcinoma.
