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 ...
Renal cell carcinoma (RCC) is a kidney cancer that originates in the lining of the proximal convoluted tubule, a part of the very small tubes in the kidney that transport primary urine. RCC is the most common type of kidney cancer in adults, responsible for approximately 90–95% of cases. [ 1 ]
Squamous-cell carcinoma (SCC), also known as epidermoid carcinoma, comprises a number of different types of cancer that begin in squamous cells. [1] These cells form on the surface of the skin, on the lining of hollow organs in the body, and on the lining of the respiratory and digestive tracts .
Renal oncocytoma is considered benign, cured by nephrectomy. There are some familial cases in which these tumors are multicentric rather than solitary. [4] However, they may be resected to exclude a malignant tumor, e.g. renal cell carcinoma.
Other malignant tumors in the kidney are transitional cell carcinoma and squamous cell carcinoma, which arise from the urothelium and are found the renal sinus, as well as adenocarcinoma, lymphoma and metastases, which can be found anywhere in the kidney (Figure 10). [1] Benign solid tumors of the kidney are oncocytoma and angiomyofibroma.
Clear cell sarcoma of the kidney (CCSK) is an extremely rare type of kidney cancer comprising 3% of all pediatric renal tumours. [1] Clear cell sarcoma of the kidney can spread from the kidney to other organs, most commonly the bone, but also including the lungs, brain, and soft tissues of the body. Despite the similarities in names, clear cell ...
The WHO/ISUP system is histological tumor grading system for renal cell carcinoma, suggested by the International Society of Urologic Pathologists (ISUP) in 2012 to diagnose tumor grades based on nucleolar prominence. [34] Currently recommended by the WHO, this four-tiered WHO/ISUP grading system has also been validated for PRCC. [34]
