The co-existence of different autoimmune disorders in the same individual is known as multiple autoimmune syndrome (MAS), which was described by Humbert and Dupond in 1988. Pathogenesis in the immune system occurs with more recurrence in patients with a background marked by another immune disorder. Around 25% of patients with immune system sicknesses tend to foster more immune disorders. In MAS, patients frequently have, at any rate, one dermatological condition, usually vitiligo or alopecia areata. Herein, we report a case of MAS in a sixteen-year-old male suffering from vitiligo with Crohn’s disease and thyroid disease.
