It can be hereditary or sporadic. The sporadic papillary renal cell carcinoma is characterized
by trisomy of chromosomes 7, 16, and 17, and loss of chromosome Y. The peak incidence
is in the sixth and seven decades. It is classified as type 1 or 2, based on the cytoplasmic
volume and the thickness of the lining neoplastic cells. The prognosis is more favorable
than for conventional (clear cell) renal cell carcinoma.;
