Hemolytic-uremic syndrome in an adult

This report describes a 45-year-old man who suffered from hemolytic-uremic syndrome. In his autopsy findings, kidney arteriolar walls showed marked hyaline degeneration and interlobular arteries were occluded by severe intimal proliferation. No vascular changes were found in other organs. There were no arteriosclerotic changes in either main branches from the aorta or the aorta. These vascular changes are correspond well with the early features of malignant nephrosclerosis without any clinical findings of malignant hypertension. This type is called primary malignant nephrosclerosis by Bohle et al. We would like to point out the significance of this case in the re-consideration of the pathogenesis of malignant nephrosclerosis.
