Inhibitory coagulopathy is a rare variant of hemorrhagic syndrome. Acquired hemophilia A is caused by the formation of inhibitors (antibodies) to Factor VIII of the blood coagulation system leading to impaired activation of the key stage of blood clotting (factor X) and development of hemorrhagic syndrome of different severity. Acquired hemophilia A is a rare disease with an incidence of 1.38-1.48 per 1 million population per year. We report a case off severe idiopathic acquired hemophilia A in a 53 year-old woman manifest as skin hemorrhages, subcutaneous and intramuscular hematomas. Hemostatic therapy described in the article resulted in the elimination of hemorrhagic syndrome and complete remission. This case represents a rare disease the knowledge of which can be useful for preventing the development of debilitating complications, and sometimes saving the patient’s life.
