Stellate Hypopigmentation in a Pediatric Patient After Treatment with Intralesionally-Injected Corticosteroid

Patient: Male, 3-year-old Final Diagnosis: Steroid-induced hypopigmentation Symptoms: Depigmentation of skin Medication:— Clinical Procedure: — Specialty: Dermatology • Pediatrics and Neonatology • Pharmacology and Pharmacy Objective: Unusual clinical course Background: Several factors contribute to keloids in post-operative patients, including skin mechanics, genetics, and inflammatory processes. One of the most widely used treatment modalities for keloidal scars involves the intralesional injection of corticosteroids, such as triamcinolone acetonide (TAC). TAC is a first-line treatment option for keloids due to its proven efficacy and effectiveness in reducing collagen synthesis, glycosaminoglycan synthesis, inflammatory processes, and proliferation of fibroblasts. Some common adverse effects of intralesional corticosteroid injection include localized hypopigmentation, depigmentation, skin atrophy, and lipoatrophy. Case Report: In this report, we describe the case of a 3-year-old African American male patient who presented for dermato-logic evaluation of a diffused stellate hypopigmentation attributed to intralesional corticosteroid injection following a keloid removal. Specifically, we summarize this case’s clinical features, diagnosis, and outcomes. Conclusions: The case illustrates self-limiting hypopigmentation that repigmented successfully without clinical intervention. Although previous reports of corticosteroid injections’ adverse effects resulting in hypopigmentation have been published, this condition is uncommon or poorly reported in pediatric patients. This report aims to contribute to our understanding of the effects of administering corticosteroids in pediatric patients by virtue of diversifying the cases reported in the currently available literature.
