CD79A and melanoma: Gene expression data from melanoma cutaneous lesion and normal skin cohorts (N = 1019 tissues) showed enhanced expression of the pan-B cell marker CD79A in melanoma compared to normal skin (Figure 3(a)) and immunohistochemical/immunofluorescence (IHC/IF) analyses showed the presence of TIL-B within clusters located adjacent to melanoma tumor islets (Figure 3(b)).
