Metastasis of Renal Cell Carcinoma Diagnosed on Fine Needle Aspiration Cytology in Cervical Lymph Node - A Case Report

Abstract

Malignant tumours with initial locations in the head and neck often metastasize to the cervical lymph nodes. These include metastasis from skin, thyroid, and salivary gland malignancies as well as SCC of the upper aerodigestive tract. Metastasis from a distant primary site accounts for around 1% of all head and neck cancers.[1]. Renal cell carcinoma represents 3% of adult malignant tumours. It is twice more in males. It is prevalent in 30 to 40% of individuals with metastatic illness and can metastasize to any part of the body. The most often afflicted organs are the liver (41%), bone (42%), local lymph nodes (66%) and lungs (76%).[2] In cases of renal cell carcinoma, extracranial head and neck metastases occur in at least 15% of cases.[3] Approximately 1% of RCC patients have metastasis that is restricted to the head and neck, and approximately 1.5–3.5% of RCC patients exhibit solitary metastasis.[4] Here, we report a case of metastasis of RCC in cervical lymph node.
