Primary sclerosing cholangitis in the presence of a lupus anticoagulant.

Lupus anticoagulant, an immunoglobulin that prolongs the partial thromboplastin time, has been associated with thrombotic events, including deep venous thrombosis, pulmonary emboli, and Budd-Chiari syndrome. In this report, primary sclerosing cholangitis was diagnosed in a man with a 10-year history of multiple thrombotic events related to a circulating lupus anticoagulant. Progressive jaundice and pruritus developed, and sclerosing cholangitis was confirmed by direct cholangiography. Sclerosing cholangitis is the second hepatobiliary disease reported in association with a lupus anticoagulant.
