Mixed connective tissue disease associated with autoimmune hepatitis and thyroiditis.

The case is reported of a 27 year old woman who had mixed connective tissue disease (MCTD) associated with chronic active hepatitis and thyroiditis. Although hepatomegaly is sometimes observed in MCTD, only four cases of MCTD and chronic active hepatitis have been described. It is thought that this is the first report of an association between MCTD, chronic active hepatitis and thyroiditis.
