title: [Clinical pathology of the glomerulus--from phenomenon to entity. The nodular-lobular lesion].
abstract: The nodular lesion in renal glomeruli develops as a localized accentuation of mesangial volume augmentation. First described by Kimmelstiel and Wilson in 1936, it was soon accepted as the characteristic form of glomerular sclerosis in patients with long-term diabetes mellitus. It has for a long time been recognized that lesions very similar to nodular glomerulosclerosis may rarely occur in patients without diabetes. Clinical and pathological investigations of such cases have shown that glomerular nodules can also develop, 1. as a sequal to light chain deposit disease associated with plasma cell dyscrasia (e.g. myelomatosis), 2. in mesangioproliferative and membranoproliferative glomerulonephritis ("lobular" GN) and 3. in some cases of glomerular amyloid deposition. A survey is given of the characteristic light microscopy, ultrastructure and immunopathology of the glomerular nodules in these diseases. The differential diagnosis and pathogenesis is discussed.
