Based on flow cytometry immunophenotyping of FNAC and histological findings of lymph node biopsy that confirmed the presence of a CD3+CD7− pathological T-cell population, and bone marrow specimens negative for lymphoid infiltration, the patient was diagnosed with a stage IIIA T-cell lymphoma not-otherwise, based on current diagnostic immunophenotypic criteria: CD4>CD8; frequent antigen loss (CD5 or CD7); CD30+/− and CD56+/−; subset follicular T helper features; and cytotoxic granules+/− [15]. Here, CD5 is linked to T-cell non-Hodgkin lymphoma.
