Background
Papillary renal cell carcinoma is a type of cancer that forms inside the lining of the kidney’s tubules.
About 5 -10% of primary renal carcinomas are papillary carcinoma.
Patients present in the third to eighth decades of life.
Like the rest of renal tumors is usually an incidental finding,
it is more frequent in men than in women.
Most are unilateral (type 1) but can occur in a multifocal or bilateral (type 2),
this finding is more prevalent than in other subtypes.
It is divided into two subtypes: type 1,
sporadic,
which appears between the fifth and eighth decades of life,
with large,
low vascularization and pleomorphism,
and type 2,
inherited,
more aggressive small,
listed in the fourth decade of life,
more vascularized and marked pleomorphism.
If the tumor is large it can also show cystic degeneration,
necrosis,
calcification,
bleeding changes and exceptional-mind,
macroscopic fat cholesterol-laden macrophages.
