The obsolescent renal glomerulus ? Collapse, sclerosis, hyalinosis, fibrosis

1977

By light and electron microscopical examination it is shown that four structural components can contribute to obsolescent glomeruli: capillary basement membranes, enriched mesangium matrix, “vascular” hyalin and collagen fibers. Each of these components can bring about glomerular damage alone. One non-reactive form — a glomerular collapse with only basement membrane remnants — can be separated from three reactive forms: the accumulation of mesangium matrix (sclerosis or matrix-sclerosis), deposition of vascular hyalin (hyalinosis in the narrow sense), and fiber development within the former urinary space (fibrosis or fibro-sclerosis). The use of the term “fibrinoid” in place of the descript…
