What is the potential side effect of long-term use of a high-potency steroid ointment in pediatric patients?

Long-term use of high-potency steroid ointments, especially in pediatric patients, can lead to skin atrophy. This condition occurs as the steroid affects the structural integrity of the skin, leading to a thinning of the epidermal and dermal layers. In children, whose skin is already more delicate and thinner than that of adults, the risk of skin atrophy is heightened.

Skin atrophy can present as changes in texture, such as increased fragility and susceptibility to injury, as well as a smooth, shiny appearance. Given that children's skin is also more dynamic and susceptible to changes, the use of high-potency steroids necessitates careful monitoring to prevent such unintended adverse effects.

While other potential side effects like skin thickening, discoloration, and changes in pigmentation are associated with steroid use, they are not as directly linked or prevalent with the long-term application of high-potency steroid ointments as atrophy is. This is why atrophy is emphasized as a primary concern in pediatric patients undergoing such treatment.
