A Newly Described Cutaneous Reaction At Sites Of Insulin Pump Use In A Child With Type 1 Diabetes

Continuous subcutaneous insulin infusion (CSII), or insulin pumps, with or without continuous glucose monitoring (CGM) devices have become the standard of care for patients with type 1 diabetes. While increasingly popular, a wide range of reported skin reactions to CSII and CGM devices was found. We present this case of a pyogenic granuloma-like neutrophilic and granulomatous response to an insulin pump to increase awareness of a previously uncharacterized cutaneous adverse reaction at insulin pump infusion sites.
