Non-symmetric subcutaneous lipomatosis associated with familial combined hyperlipidaemia.

A family with familial combined hyperlipidaemia in which affected members had nonsymmetric subcutaneous lipomatosis (NSSCL) is described. Affected members had high serum levels of total cholesterol, low density lipoprotein (LDL) cholesterol and high density lipoprotein (HDL) cholesterol. By contrast, family members without NSSCL had normal lipid levels. There was also a correlation between the degree of hyperlipidaemia and the amount of subcutaneous lipomas. The occurrence of hyperlipidaemia in family members with NSSCL suggests the existence of a genetic linkage between these two characteristics, but did not show any association with HLA haplotyping. To our knowledge this association between lipid abnormalities and NSSCL has not been previously reported.
