Abstract
- Acquired hemophilia is a rare disease caused by an autoimmune reaction to coagulation factor VIII, The mortality rate of this disease is very high (8~22%). Clinical manifestations are different from congenital hemophilia. Various diseases are associated with acquired hemophilia, including autoimmune diseases such as systemic lupus erythematosus or rheumatoid arthritis (RA), tumors, inflammatory bowel disease, psoriasis, asthma, diabetes, acute hepatitis B or C, and drug reactions. However, the underlying cause is unknown in approximately 50% of cases. A few cases of acquired hemophilia with RA have been published. However, no cases have been reported in Korea. We had a patient with longstanding RA and acquired hemophilia who was suffering from upper and lower extremity purpura with a deep intramuscular hematoma. The patient was successfully treated using cyclophosphamide combined with steroid.
