CTSK and MIT family translocation renal cell carcinoma: Negative expression of parvalbumin (p = 0.0001) and positive staining for CD10 (p = 0.0001 with a 5% cutoff, p = 0.0004 with a 10% cutoff, and p = 0.0070 with a 20% cutoff), AMACR (p = 0.0001), CD13 (p = 0.0001), and cathepsin K (p = 0.0001) were strongly statistically consistent with the diagnosis of MiT family translocation renal cell carcinoma despite what positivity threshold was used.
