Nodular regenerative hyperplasia of the liver and antiphospholipid antibodies: report of two cases and review of the literature.
Nodular regenerative hyperplasia of the liver (NRHL) is a rare disorder characterized by diffuse micronodular transformation of the hepatic parenchyma without fibrous septa between the nodules. This condition appears to be associated in many occasions with systemic autoimmune diseases. We describe two new patients with NRHL in whom antiphospholipid antibodies (aPL) were detected in their sera and review the few similar cases reported previously. We also discuss the possible relationship between aPL and NRHL and suggest that these antibodies may play a role in the pathogenesis of some cases of NRHL, specially those with an associated antiphospholipid syndrome.
