[Chorea and systemic lupus erythematosus].

The appearance of chorea due to systemic lupus erythematosus is extremely rare. A greater frequency of circulating anticoagulant, false positive luetic serology and antiphospholipid antibodies has been recently detected in these patients. For this reason, it has been postulated that these could be involved in the genesis of the chorea through a thrombotic mechanism or autoimmune encephalitis. We describe a case or chorea in a female patient with systemic lupus erythematosus.
