Table 6. Active and chronic glomerular lesions

Active lesions
    Endocapillary hypercellularity with or without leukocyte infiltration and with substantial luminal reduction
    Karyorrhexis
    Fibrinoid necrosis
    Rupture of glomerular basement membrane
    Crescents, cellular or fibrocellular
    Subendothelial deposits identifiable by light microscopy (wireloops)
    Intraluminal immune aggregates (hyaline thrombi)
Chronic lesions
    Glomerular sclerosis (segmental, global)
    Fibrous adhesions
    Fibrous crescents
