Abstract
A family with hereditary autosomal dominant hypofibrinogenemia is described. The outstanding feature is massive deposition of fibrinogen/fibrin within hepatocytes, faintly visible in routine microscopic sections, but clearly demonstrable by immunohistologic techniques. Circulating fibrinogen shows normal electrophoretic mobility of Aα-, Bβ-, and γ-chains. We assume that the hereditary defect in this family interferes with fibrinogen release from hepatocytes. Clinically there are fluctuating slight elevations of serum transaminase levels. Hemostasis and wound healing are undisturbed.
