Linear Hypopigmentation Following Subcutaneous Steroid Injection.

A 78-year-old woman presented to the dermatologist with linear hypopigmentation four weeks after a local corticosteroid injection. Corticosteroid injections are commonly used for various musculoskeletal conditions refractory to other conventional treatments. We discuss a case report of a patient with linear hypopigmentation in the perilymphatic distribution due to local corticosteroid injection for the treatment of carpal tunnel syndrome (CTS). Providers who routinely inject corticosteroids should discuss this rare complication prior to injections.
