What Autoimmune illnesses are you suffering with EM?

I have Vitiligo my father has vitiligo and my mother has ulcerative colitis so I was wondering what autoimmune illnesses do you suffer from?

I have an undifferentiated connective tissue disease (meaning I have a systemic autoimmune disease, but they don't have a specific name for it). It is assumed my EM is secondary to the autoimmune disease.
