Reversible Hypopigmentation and Atrophy After Corticosteroid Injection in De Quervain’s Tenosynovitis

ABS TRACT De Quervain tenosynovitis is a stenosing tenosynovitis that occurs as a result of repetitive movements and overuse of the abductor pollicis longus and extensor pollicis brevis tendons located in the 1st dorsal compartment of the wrist.Conservative methods are used 1st in the treatment.Physical therapy methods, splints for immobilization, nonsteroidal anti-inflammatory drugs, and corticosteroid (CS) injections are used to reduce irritation and inflammation in the tendons.Skin hypopigmentation and subcutaneous adipose tissue atrophy are the dermal side effects of CS injections.In this case report, we aim to present a case in which reversible subcutaneous adipose tissue atrophy and skin hypopigmentation developed on the radial side of the wrist after triamcinolone acetonide injection performed with a blind technique in the treatment of De Quervain tenosynovitis and to make recommendations on this subject.
