Nasal type NK/T-cell lymphoma arises as consequence of malignant transformation of NK-cells (NKC) which express markers CD 56+ (Neural cell adhesion molecule), TIA (T-cell intracellular antigen-A), and lack T-cell receptor (TCR) gene rearrangements, hence distinguishing the tumour from T-cell lymphomas [7,8]. This evidence concerns the gene CHL1 and T-cell non-Hodgkin lymphoma.
