In 1942 Marble and Smith1 reviewed the literature and studied 500 unselected diabetic patients, almost one fifth of whom were found to have areas of lipoatrophy at the site of the insulin injections. After careful histologic studies and other investigations, they could prove no relationship to any of the factors involved in the administration of insulin except possibly that of repeated trauma.
In my personal experience the incidence of insulogenic lipodystrophies reaches close to 60 per cent of all diabetic patients who have been taking daily injections of insulin for periods longer than six months before coming to my
