Question:

Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Kidney: How many primaries, with what histology(ies) should be coded when nephrectomy pathology specimen shows separate tumors of "renal cell carcinoma [clear cell type]" and "renal cell carcinoma [granular cell type]"?

Discussion:

Answer:

For tumors diagnosed prior to 2007:

Abstract two primaries. This is an example of two tumors with different histologic types in the same site. The right kidney has two separate tumors.

8310/3 [renal cell carcinoma (clear cell type)]

8320/3 [renal cell carcinoma (granular cell type)]

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
