The association of autoimmune pathologies with cutaneous diseases has received little attention, except for their association by twos. The combination of at least three autoimmune diseases in a same patient has recently been defined as a Multiple Autoimmune Syndrome (MAS). The purpose of this article is to define the place of dermatological autoimmune conditions (vitiligo, alopecia areata, pemphigus, bullous pemphigoid, dermatitis herpetiformis) among the MAS and to stress the clinical aspects that may aid dermatologists in the care of their patients.
