The overall FoxP3+ cell quantity was significantly lower (p = 0.01) in the nodal PTCL cohort (median: 255 FoxP3+ cells/mm2; range: 4–2037 FoxP3+ cells/mm2) compared to the reactive LN cohort (median: 431 FoxP3+ cells/mm2; range: 199–791 FoxP3+ cells/mm2) (Figure 3). Here, FOXP3 is linked to mature T-cell and NK-cell non-Hodgkin lymphoma.
