Ribociclib-induced extensive vitiligo-like lesions: possible pathomechanisms with clinical, dermoscopic and histological correlation

Abstract

Cyclin dependent kinase (CDK) 4/6 inhibitors are targeted agents which act on cyclin-D and these combined with hormonal therapy have been approved for the treatment of locally advanced or metastatic breast cancer. CDK 4/6 inhibitors have been found to have a tolerable adverse event profile; however, they have been associated with various dermatological adverse events. We report a case of ribociclib-induced vitiligo and discuss the clinical, dermoscopic and histological features with a review of the various possible pathomechanisms involved.
