label_lc: glomerular amyloid subepithelial deposits
description: "A type of fibrillar glomerular subepithelial deposit characterized by extracellular aggregates composed of fine, randomly oriented, non-branching fibrils 8-12 nm in diameter, often forming a cottony mass. This feature is associated with a prominent glomerular basement membrane (GBM) reflecting an diffuse and relatively uniform increase in thickness (subjective estimate)."
