CD79A and lobular neoplasia: Thus, according to the concordant results of the literature, we can accept that marked intense staining is observed in proliferative GN characterized by intense glomerular cellular proliferation such as observed in crescentic GN, i.e., Lupus nephritis (LN) and ANCA associated vasculitis, whereas less intense staining is detected in less proliferative GN, i.e., IgA and membranous nephropathy [48,49,50].
