Vitiligo Following COVID-19 Vaccination and Primary Infection: A Case Report and Systematic Review.

Vitiligo is an acquired pigmentation disorder with different theorized etiologies, although the exact pathogenesis is still largely unknown. It presents as well-demarcated white plaques throughout the body that result from the loss of melanocytes within the epidermis. Commonly, this condition presents alongside other autoimmune conditions, and it is associated with both genetic and non-genetic factors. We present a patient with no history of autoimmune disease who developed vitiligo after receiving her vaccines against COVID-19. This first occurred within 24 hours of receiving her first vaccine and then worsened after receiving her second vaccine. The depigmented rash was localized to the face, arms, and chest. She was treated with both oral and topical steroids, as well as topical tacrolimus cream. Despite adherence to treatment, the patient only reported subjective improvement in her skin lesions overall. While vitiligo arises sporadically, the temporal relationship between vaccinations and depigmentation makes a stronger case for the vaccine as the inciting factor for this patient, though coincidence is possible. A systematic review of the literature regarding the onset of vitiligo following both infection with and vaccination against COVID-19, this case offers a unique presentation that had a sudden onset and creates a learning opportunity for clinicians to investigate the potential relationship between the receipt of the vaccine and the onset of this skin condition. The goal of this report is to help clinicians be cognizant of the possibility of developing or worsening skin diseases after infection or vaccination so that they can be addressed and treated appropriately.
