Abstract
Two cases of lymphoma-associated acquired C 1-inhibitor deficiency are described. In both patients, C 1-inhibitor deficiency and related symptoms preceded the diagnosis of the underlying neoplasm by several months. C 1-inhibitor deficiency was most likely due to consumption following immunocomplex formation. In both patients, a close relationship between low levels of C 1-inhibitor and tumor relapse was observed during follow-up. These findings indicate that measurement of C 1-inhibitor and complement factor C4 can be used as markers of disease activity in affected patients.
