Abstract:
:This presentation reports the light and electron microscopic findings relating to the vascular and glomerular changes in the kidney in a series of 25 patients having malignant hypertension, the hemolytic-uremic syndrome, scleroderma, or toxemia of pregnancy. The pathologic changes were generally similar in each of the diseases studied, the changes being related more to the severity and duration of injury than to the specific disease. Vascular narrowing was due mainly to intimal thickening, and by light microscopy the lesions were categorized as onionskin, mucinous, or fibrous with or without associated elastosis. Intimal erythrocyte extravasation, fibrinoid necrosis, and luminal thrombosis were also seen. Electron microscopy provided additional morphologic information: Myointimal cells were found to be the cellular component in each type of intimal thickening; it was possible to distinguish collagen from large intimal accumulations of basement membrane material; mucinous intimal material was characterized ultrastructurally; and fibrinoid necrosis was identified as a lesion inconstantly associated with cellular necrosis and consisting mainly of fibrinoid material and small deposits of fibrin. It seems likely that there is a common pathogenesis for intimal thickening in a variety of diseases and that this involves endothelial cell damage and increased permeability, leakage of serum and erythrocytes into the intima, and a healing reaction of the vessel wall was developing from migration of smooth muscle cells into the intima with subsequent myointimal cell proliferation and fibrogenesis. A common glomerular change in all diseases studied was a striking accumulation of electron lucent material between the endothelium and the lamina densa of the basement membrane. This lesion was interpreted as a manifestation of acute ischemia.
