Weiss et al. [20] reported on a 6-year-old patient with NK cell-like T-cell lymphoma restricted to the jejunum; the tumour cells were positive for CD3 and CD56 and negative for CD4, CD8 and CD30, and there was no EBV infection, similar to type II EATL. This evidence concerns the gene NCAM1 and Epstein-Barr virus infection.
