The aim of our study is to evaluate the quantity and prognostic value of FoxP3+ cells in the TME of 101 patients diagnosed with nTFHL-AI (all patterns), nTFHL-F, nTFHL-NOS, PTCL-NOS, and CL and compare them with the reactive LN patient cohort. Here, FOXP3 is linked to mature T-cell and NK-cell non-Hodgkin lymphoma.
