Type 1 PRCC, also known as a renal tumor caused by a genetic predisposition of hereditary papillary renal cancer syndrome, compromises approximately 25% of all PRCCs. [14] [15] In the perspective of immunochemistry, it has a profile of strong CK7 and alpha-methyl acyl-CoA racemase (AMACR) expression at most focal CA-IX expression. [16]
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.
Psammoma bodies are commonly seen in certain tumors such as: Papillary thyroid carcinoma [2]; Papillary renal cell carcinoma [3]; Ovarian papillary serous cystadenoma and cystadenocarcinoma [4]
Metanephric adenoma (MA) is a rare, benign tumour of the kidney, that can have a microscopic appearance similar to a nephroblastoma (Wilms tumours), [1] or a papillary renal cell carcinoma. It should not be confused with the pathologically unrelated, yet similar sounding, mesonephric adenoma .

Congenital mesoblastic nephroma was first named as such in 1967 but was recognized decades before this as fetal renal hamartoma or leiomyomatous renal hamartoma. [4] It is embryologically derived from the metanephrogenic blastema , the same tissue that gives rise to nephroblastomatosis and Wilms tumor .
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 ]
They cannot be reliably differentiated from low grade papillary urothelial carcinomas using cytology, [1] and their diagnosis (vis-a-vis low grade papillary urothelial carcinoma) has a poor inter-rater reliability. [2] Pathologic grading and staging tumors are: graded by the degree of cellular atypia (G1->G3), and staged: [citation needed ...
