Papillary Renal Cell Carcinoma (PRCC) is a type of kidney cancer that originates in the renal tubules. It is characterized by the presence of finger-like projections, or papillae, in the tumor tissue. PRCC accounts for about 10-15% of all renal cell carcinomas and is often diagnosed in individuals between the ages of 50 and 70. There are two main subtypes of PRCC: type 1 and type 2, which differ in their cellular characteristics and aggressiveness. Symptoms may include blood in the urine, flank pain, and unexplained weight loss. Treatment options typically involve surgery, targeted therapy, or immunotherapy, depending on the stage of the disease.
