In terms of morphology, the proportion of cystic component in ccRCC with cystic component similar to MCRN-LMP showed a continuous spectrum from 20 to 90%, which also provides one evidence for continuous progress from MCRN-LMP to ccRCC with cystic component similar to MCRN-LMP. This evidence concerns the gene PDLIM7 and nonpapillary renal cell carcinoma.
