Fig. 2From: Large cell morphology, CMYC+ tumour cells, and PD-1+ tumour cell/intense PD-L1+ cell reactions are important prognostic factors in nodal peripheral T-cell lymphomas with T follicular helper markersImmunohistological findings of patients with large cell PTCL-TFH. Atypical large lymphoid cells are diffusely positive for PD-1 (a), CXCL13 (b), CMYC (c) and PD-L1 (d). PD-L1+ tumour cells, dendritic and histiocytic cells are admixed.
