Case report: Drug-induced vitiligo during treatment with BRAF/MEK inhibitors in a patient with metastatic conjunctival melanoma

Abstract

Introduction

Autoimmune side effects can be detected during the use of BRAF/MEK inhibitor. Although its frequency, mechanism and importance are not known exactly, there are cases reported in the literature.

Case Report

We report a case of drug-induced vitiligo in a patient with metastatic conjunctival malignant melanoma who was treated with BRAF/MEK inhibition therapy.

Management and Outcome

In the case, vitiligo was controlled with topical treatments. Follow-up process of the patient has been continuing with no progression on month 12 of the current treatment.

Discussion

Although ICI-related autoimmune side effects and vitiligo have been described more frequently, vitiligo may also occur secondary to BRAK/MEK inhibition. This case also points out that cutaneous toxicity is manageable with no delay in treatment thanks to collaboration of dermatologists and oncologists.
