Membranous with FSGS
Some patients with membranous glomerulopathy also have associated focal segmental glomerulosclerosis (FSGS) lesions. The glomerulus in this biopsy image, for example, shows a prominent area of segmental sclerosis surrounded by mildly thickened capillary loops which have granular IgG deposits by immunofluorescence (see inset). As in other renal diseases, studies have linked the presence of FSGS lesions in patients with membranous glomerulopathy to more severe disease (e.g. higher levels of proteinuria).
