Individuals with hereditary protein C deficiency can present with venous thromboembolism (VTE), warfarin-induced skin necrosis in adults, and neonatal purpura fulminans in newborns who are homozygous or compound heterozygous for protein C mutation. Obtaining a detailed history that focuses on personal history—including previous history of thrombosis and any abnormal laboratory results—fmailiy history, and obstetric history is paramount.
