Multilocular Cystic Renal Cell Carcinoma
Supplemental Studies
Immunohistology
- Keratin or EMA stain may be useful for identification of nests in septa
- Some differences compared to usual clear cell carcinoma but they are not great enough to be useful
(Williamson 2012)
- CK7 is more frequently positive (92 vs 38%)
- Racemase (AMACR) is less frequently positive (21 vs 67%)
Genetic Study
- Most show 3p deletions
- Similar to clear cell renal cell carcinoma
