The prevalence of diabetes mellitus has been steadily increasing worldwide. Management of diabetes has been revolutionised with the advent of newer medical devices for continuous insulin infusions and glucose monitoring. However, this has led to an increase in contact dermatitis to various components of the devices. Recent investigations in Europe have identified isobornyl acrylate as the culprit in many instances.
We present a case of a 26 year old woman with type 1 diabetes who had allergic contact dermatitis to the adhesive component of her continuous glucose monitoring device.
We discuss the recent literature on isobornyl acrylate, its possible cross reactions with other acrylates and the difficulties and pitfalls in patch testing.
