Demonstrates unusual cervical lymph node metastasis in renal cell carcinoma, suggesting careful diagnostic approaches are needed.
The fine-needle aspiration (FNA) technique has emerged as a rapid diagnostic modality in diagnosis of metastatic tumors of unknown primary. Renal cell carcinoma (RCC) is well known for its potential to metastasize to remote sites. However, RCC primarily presenting with cervical lymph node metastasis is an unusual phenomenon. Herein, we describe a case of RCC with cervical lymph node metastasis as the initial clinical presentation, which was diligently diagnosed in FNA smears by appreciating the classic cytomorphological features and with wise use of an immunocytochemical panel.
