Autoimmune sequential overlap syndrome (autoimmune hepatitis/primary sclerosing cholangitis) and inflammatory bowel disease: three clinical cases.

Inflammatory bowel disease (IBD) is related to different liver extraintestinal manifestations and occurs with or without a link to disease activity. Primary sclerosing cholangitis (PSC) is the most common hepatobiliary manifestation. Other autoimmune hepatopathies may develop during the evolution of the latter, which is known as overlap syndrome.
