Abstract |
Homozygous protein C deficiency is a rare herediatary disorder of blood coagulation resulting in microvascular and venous thromboses, usually purpura fulminans, starting shortly after birth. Protein C serves to inactivate the active forms of factor V and VIII, and increase the rate of fibrin degradation. For confirmation of homozygous protein C deficiency, the infant should have undetectable protein C activity and both parents should be heterozygous for protein C deficiency.
We experienced a case of purpura fulminans due to homozygous protein C deficiency, which first apperared at age 14 hours with sudden onset of large ecchymoses on both flanks, buttocks, and thighs, and rapidly progressed. We confirmed the case by protein C study for patient and her family members, and report with the brief review of the literature. |
