A previously unknown, rapidly fatal disorder of infancy characterized by markedly increased serum triglycerides, pancytopenia, hepatosplenomegaly, and neutral-fat-containing granuloma-like cell infiltrates in various organs was reported by us in a short communication in 1961.15 In the present paper a full report of our original case will be given as well as available data about an older sister, who had died in infancy a few years earlier with an almost identical clinical picture. Re-examination of the microscopic material showed the same histological picture. In addition, fat-loading tests on the healthy members of the family will be presented.
