Fatty liver hepatitis and type 5 hyperlipoproteinemia in juvenile diabetes mellitus. Case report and review of the literature.

A 28-year-old man with poorly controlled juvenile-onset diabetes mellitus presented with jaundice and type 5 hyperlipoproteinemia. A liver biopsy showed fatty liver hepatitis (steatonecrosis). This case represents one end in a spectrum of lipid disorders and liver disease in diabetes mellitus. With increasing insulin deficiency, liver steatosis and the more common type 4 hyperlipoproteinemia pattern may progress to fatty liver hepatitis and type 5 hyperlipoproteinemia.
