Characterization of infiltrating immune contexture. (a) RMS10 with a PD-L1 scoring of TC0 and IC2 in the areas surrounding the tumor with a faint staining and in a focal pattern (as pointed out by the arrows). (b-e) Magnification (40X) of the area within the box, displaying different IHC expression staining: (b) PD-L1(Clone 1SP124) expression in the immune contexture and not in tumor cells, (c) Myogenin positive expression of neoplastic cells, (d) CD3 revealing T-lymphocytes positivity, (e) and CD68 staining confirming macrophages positivity
