A very rare case report:Renal cell carcinoma metastasizing to the tonsil after 5 years of radical nephrectomy

Abstract

Renal cell carcinoma (RCC), is the most common kidney cancer, that accounts for approximately  90% of all adult renal malignancies with 30% of patients presenting with metastasis at initial diagnosis.There are several reports of metastases developing after 10-20 years even if curative nephrectomy has been made. Clear cell (60%-75%), papillary (10%-15%), chromophobe (5%), and collecting duct carcinoma are well characterized subtypes of RCC.Renal cell carcinoma mainly metastasizes to the lungs,the bones,the liver,the lymph nodes and brain.Metastasis to the head and neck region is rare.In this case report we present a tonsil metastasis after 5 years of nephrectomy.Surgery with histopathological examination confirmed that metastasis of clear cell carcinom.The patient was successfully treated by surgery and referred to oncology.Later he was out of our follow-up.
