In Fig. 5 we elaborate on the patterns of IHC that may be helpful when used in conjunction with TRIM63 RNA-ISH; in particular, a moderate H-score for TRIM63 RNA-ISH in combination with broad (multiple marker) and strong myomelanocytic marker staining would favor a diagnosis of PEComa over ASPS. Here, TRIM63 is linked to neoplasm with perivascular epithelioid cell differentiation.
