Abstract excerpt

The expression of T-follicular helper (TFH) markers, initially described in nodal T-cell lymphomas arising from TFH-cells, has been reported in several non-TFH lymphomas, including B-cell lymphomas. It has also been observed in marginal zone lymphomas (MZL), whereas it is poorly characterized in nodal MZL (NMZL). The present study, therefore, aimed to characterize MZL with TFH cell expansions, by providing an...
