Depigmentation--a rare side effect to intra-articular glucocorticoid treatment.

Intra-articular glucocorticoid injections are often used in patients with rheumatoid arthritis, either as bridging therapy or in periods with increased disease activity. We present a case of local skin depigmentation that occurred at the site of injection in a dark-skinned patient. Depigmentation is a rare complication of such therapy but may have important implications for dark-skinned patients.
