A new combination of multiple autoimmune syndrome? Coexistence of vitiligo, autoimmune thyroid disease and ulcerative colitis

Abstract

The occurrence of three or more autoimmune disorders in one patient defines multiple autoimmune syndrome. The pathogenesis of multiple autoimmune syndrome is not known yet and environmental triggers and genetic susceptibility have been suggested to be involved. Herein, we report a 47-year-old woman who had Hashimoto’s thyroiditis, vitiligo and newly diagnosed ulcerative colitis. Diagnosis of ulcerative colitis was confirmed with histopathologic examination. This case presents a new combination of multiple autoimmune syndrome.
