We present here a review article dealing with immunohistochemistry and basic molecular-genetic findings/markers in selected renal tumors. The article is not an universal instruction for renal tumor diagnostics.
Renal cell carcinomas can have very variable morphological features (even within one neoplastic lesion - i.e. tumoral heterogeneity) and unpredictable and variable immunohistochemical profile. Some renal neoplasias are diagnosed on the base of molecular-genetic signs only (regardless morphologic appearance).
