Intralesional corticosteroid-induced hypopigmentation and atrophy

Area of Science:

• Dermatology
• Pharmacology

Background:

• Intralesional corticosteroids are frequently used for various dermatological conditions.
• Common adverse events are typically localized to the injection site.

Observation:

• A rare adverse event of corticosteroid injections was observed.
• The event presented as outward radiation in a linear, streaky pattern.

Findings:

• The observed adverse event was characterized as perilesional/perilymphatic hypopigmentation or atrophy.
• This pattern differs from the commonly localized skin changes.

Implications:

• This case expands the understanding of uncommon corticosteroid injection side effects.
• Clinicians should be aware of this rare presentation to ensure accurate diagnosis and patient counseling.
