Abstract
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.
Highlights
Corticosteroid injection is frequently used for the control of inflammation of the ganglion, tenosynovitis, De Quervain's disease, joint, tendon, and ligament etc
[2] Hypopigmentation after intralesional injection of triamcinolone acetonide has been reported in the literature as a very rare side effect
[2] In this article, we report a case who met hypopigmentation after local corticosteroid injection
Summary
Corticosteroid injection is frequently used for the control of inflammation of the ganglion, tenosynovitis, De Quervain's disease, joint, tendon, and ligament etc. Compared to systemic corticosteroid injection, the incidence of complications after local corticosteroid injection is extremely low with an estimated risk of less than 1% [1]. Cutaneous changes after local corticosteroid administration may include dermal atrophy, hyperpigmentation, alopecia, and hypopigmentation. [2] Hypopigmentation after intralesional injection of triamcinolone acetonide has been reported in the literature as a very rare side effect. [3] The exact pathogenesis of hypopigmentation is unknown.
