Hypopigmentation After Local Corticosteroid Injection for De Quervain Tenosynovitis

The clinical presentation hypopigmentation is a rare complication after intralesional injection of triamcinolone acetonide. A 32-year-old female, yellow race, visited our dermatology department for a hypopigmented patch in right dorsum of her right thumb. The lesion developed after injection of an intralesional corticosteroid. The patient was diagnosed with hypopigmentation secondary to the triamcinolone injection. Three months after injection, her hypopigmentation showed improvement upon physical examination. Hypopigmentation is a very rare side effect of intralesional triamcinolone injection, which may be associated with gender. The mechanism is unknown, need for further study.
