In contrast, cases with TCR γδ are CD4 –, CD8 – and CD56 + and may involve the epidermis and have a poor prognosis.[2–4] On this basis, according to the WHO-EORTC classification, SPTCL is restricted to cases with αβ TCR and those with TCR γδ are placed in a new category of primary cutaneous peripheral T cell lymphomas—cutaneous γ T-cell lymphoma.[2]. Here, NCAM1 is linked to T-cell non-Hodgkin lymphoma.
