Linear rays of hypopigmentation following intra-articular corticosteroid injection for post-traumatic degenerative joint disease.

Intra-articular and intralesional glucocorticoid injections are commonly used by dermatologists, orthopedic surgeons, and rheumatologists because they offer many advantages over oral or parenteral dosage forms. Triamcinalone acetonide is a frequently utilized glucocorticosteroid for intra-articular injections, yet there are a limited number of case reports describing cutaneous hypopigmentation as an adverse effect. Here we present a unique case of hypopigmentation with a linear ray distribution demonstrating lymphatic collection and spread of the triamcinalone acetonide.
