A type of glomerular subepithelial deposit characterized by finely granular material deposited between the outer (epithelial) aspect of the glomerular basement membrane (GBM) and the visceral epithelial cell, with varying degrees of incorporation into the GBM and corresponding to immunoglobulin and/or complement by immunofluorescence/immunohistochemistry. This feature is associated with a prominent GBM reflecting an diffuse and relativly uniform increase in thickness (subjective estimate). [KPMP:arosenberg, PMID:32866505]
