Flow cytometric findings in non-T cell lymphoma. (A) CD4+ T cells with CD10 and bright PD-1 expression were observed in follicular lymphoma. (B) CD4+ T cells with CD200 and bright PD-1 expression were seen in tuberculous granuloma. (C) Expansion of CD4+T cells with bright PD-1 expression was present in nodular lymphocyte-predominant Hodgkin lymphoma. (D) CD4+ T cells with distinctive bright PD-1 expression were observed in reactive follicular hyperplasia. TRBC1 was polyclonal in these populations.
