Vitiligo is an acquired idiopathic pigmentary skin disorder characterized by the development of white macules and patches due to the loss of functioning melanocytes. In this report, we describe a case of a patient with a longstanding history of dermatitis herpetiformis (DH) and celiac disease that developed rapidly progressing, biopsy-confirmed generalized vitiligo after 11 months of treatment with anti-inflammatory medication sulfasalazine, prescribed for the patient's DH. To the best of our knowledge, this is the first case report which has demonstrated the possible biochemical pathways, triggered by sulfasalazine, in the development of vitiligo.
Keywords: celiac disease; dermatitis herpetiformis; generalized vitiligo; sulfasalazine.
