Successful treatment of insulin lipoatrophy. A case report.

: Widespread subcutaneous lipoatrophy developed in a nineteen year old female diabetic using subcutaneous bovine NPH insulin. Neither rotation of the injection site nor injection of the same insulin into the atrophic areas affected the lesions. Replacement of the bovine insulin by a porcine preparation given by deep intramuscular injection into the center of the atrophic areas resulted in disappearance of the lesions within a short time.
