title: Factor V deficiency in a patient with rheumatoid arthritis.
abstract: Factor V deficiency associated with rheumatoid arthritis was found in a 54-year-old woman. Hereditary factor V deficiency is very rare; only about 150 cases have been reported since its discovery in 1943. This appears to be the first case report of factor V deficiency associated with rheumatoid arthritis in the literature.
