Cushing Syndrome from Percutaneous Absorption of 1% Hydrocortisone Ointment in Netherton Syndrome

Abstract

Netherton syndrome is a congenital skin disease associated with decreased skin barrier function and increased percutaneous absorption. We report an 11-year-old boy with Netherton syndrome who developed Cushing syndrome after application of 1% hydrocortisone ointment to his entire body for more than 1 year. This presentation illustrates that even low-potency steroid ointments should be used with caution in Netherton syndrome and warns about the use of long-term topical medications with potential systemic side effects when used in large quantities in any chronic skin disease.
