title: Fitzgerald factor: a hitherto unrecognised coagulation factor.
abstract: A newly recognised asymptomatic coagulation-factor deficiency is reported in a 71-year-old man. This factor seems to operate at an early stage in the intrinsic coagulation pathway and participates in other Hageman-factor-mediated biological reactions. The patient has an atypical cellular inflammatory response as observed by the skin-window technique.
