Renal Terms

Several subtypes of kidney cancer have also been reported in the Mainz classification of renal tumors (PDF). Note (see below) that the NOS term, 8312/3 Renal cell carcinoma, NOS, is actually a higher number than one of the subtypes. This is an exception to the convention that subtypes generally have a higher number than the NOS term. Note also that "papillary renal cell carcinoma" is a synonym for "papillary adenocarcinoma" (8260/3).
