So far, the literature data have presented a combination of several autoimmune triggered disease in patients, but the research is scarce and very limited. In this context we present a rare case of autoimmune thyroiditis with a concomitant autoimmune hepatitis. Hashimoto thyroiditis is an autoimmune disorder in which immune cells lead to impairment, destruction of the thyroid hormone producing cells and tissue fibrosis with consecutive primary hypothyroidism. Autoimmune hepatitis is a chronic liver disease with unknown etiology, which is assumed to be T cell mediated condition where immune cells produce autoantibodies responsible for inflammation, destruction and fibrosis of the hepatic parenchyma. In this case report, we discuss the possible correlation in the spectrum of autoimmune diseases concerning Hashimoto thyroiditis and autoimmune hepatitis.
