Abstract
Nodular regenerative hyperplasia of the liver (NRHL) has been found in association with collagen vascular diseases, after drug therapy, with autoimmune disease, and with a variety of haematological disorders. The association of NRHL with the syndrome of Calcinosis cutis, Raynaud's phenomenon, oesophageal dysfunction, sclerodactyly and telangiectasia (CREST syndrome) has only been reported on two previous occasions. The liver disease usually associated with CREST syndrome is primary biliary cirrhosis (PBC) and recently nodular hyperplasia of the liver has been reported in patients with early stage PBC. We present a case of NRHL with CREST syndrome and serological and biochemical features of PBC, a newly recognised overlap syndrome.
