Abstract/OtherAbstract:
Nasal and nasal-type NK/T-cell lymphomas are predominantly extranodal tumors with a specific immunophenotype and a strong association with EBV. The cutaneous lymphocyte-associated antigen (CLA) is the homing receptor for skin-homing T cells and NK cells. In the literature, the prognostic impact of CLA expression in primary cutaneous T-cell lymphomas and nasal NK-cell lymphomas is contradictory. We present 2 non-nasal NK-cell lymphomas with nodal presentation. Both tumors showed the phenotype of CD3+ (cytoplasmic), CD5-, CD7-, CD16+, CD56+, cytotoxic molecules+, EBV+ (by in situ hybridization), and CLA+. They were polyclonal for T-cell receptor gamma chain gene rearrangement, indicating an NK cell lineage. The aggressive course in these two patients suggested that in nasal and nasal-type NK-cell lymphomas, CLA expression might be an indicator of poor prognosis. More studies are needed to elucidate the prognostic impact of CLA expression in T cell and NK-cell lymphomas.
