Metastatic renal cell carcinoma (mRCC) is the spread of the primary renal cell carcinoma from the kidney to other organs. Approximately 25–30% of people have this metastatic spread by the time they are diagnosed with renal cell carcinoma. [ 101 ]
A solid renal mass appears in the US exam with internal echoes, without the well-defined, smooth walls seen in cysts, often with Doppler signal, and is frequently malignant or has a high malignant potential. The most common malignant renal parenchymal tumor is renal cell carcinoma (RCC), which accounts for 86% of the malignancies in the kidney.

The most frequent, malignant, primary kidney cancer is renal cell carcinoma (RCC) - which has several subtypes: Clear cell RCC, an epithelial cell tumour of the kidney that accounts for 65-70% of all RCCs. [5] Papillary RCC, a renal tumour that accounts for 10-15% of all RCCs. Males are 1.5 times as likely to develop this type of tumour than ...
Papillary renal cell carcinoma (PRCC) is a malignant, heterogeneous tumor originating from renal tubular epithelial cells of the kidney, which comprises approximately 10-15% of all kidney neoplasms. [1] Based on its morphological features, PRCC can be classified into two main subtypes, which are type 1 and type 2 (eosinophilic). [2]
A 2006 review stated that Reed's Syndrome often is the leading cause of renal cancer between ages 30–50. Renal cancer kills about 1 in 3 people, but 5-year survival rates improved between 1974–1976 and 1995–2000, from 52% to 64%. [18]
Generally, the cells have a clear cytoplasm, are surrounded by a distinct cell membrane and contain round and uniform nuclei. [citation needed]Microscopically, CCRCCs are graded by the ISUP/WHO as follows: [1] [2]
Clear cell papillary renal cell carcinoma (CCPRCC) is a rare subtype of renal cell carcinoma (RCC) that has microscopic morphologic features of papillary renal cell carcinoma and clear cell renal cell carcinoma, yet is pathologically distinct based on molecular changes and immunohistochemistry.
