Abstract

Among Epstein-Barr virus (EBV)-positive cytotoxic T/NK-cell lymphoma, there are only a few reports on the clinicopathologic features of patients with primary nodal presentation (nodal EBV+ cytotoxic T-cell lymphoma [CTL]). Here, we compared the clinicopathologic profiles of 39 patients with nodal EBV+ CTL with those of 27 cases of "extranasal" NK/T-cell lymphoma of nasal type (ENKTL), especially addressing their T-cell receptor (TCR) phenotype. Histologically, 22 of 39 nodal EBV+ CTL cases (56%) were unique in having centroblastoid appearance, which was contrasted with the lower incidence of this feature in ENKTL (15%, P=0.001). In contrast, pleomorphic appearance was more frequently seen in ENKTL than in nodal EBV+ CTL (67% vs. 23%, P=0.001). Thirty-three of 39 nodal EBV+ CTL cases (85%) were of T-cell lineage on the basis of TCR expression and/or TCRγ gene rearrangement; in detail, 18 cases (46%) were TCRβ positive (αβ T), 5 (13%) were TCRγ and/or δ positive (γδ T), and 10 (26%) were TCR-silent type with clonal TCRγ gene rearrangement but no expression of TCRβ, γ, or δ. These results were clearly contrasted by a lower incidence of T-cell lineage in ENKTL (7 cases, 26%, P+ CTL is distinct from ENKTL.
