title: [Negative antinuclear antibodies in disseminated lupus erythematosus. Report of 3 cases].
abstract: There are described 3 cases of patients with LED in which the obtained results of AAN's research, by means of IFI, were negative in a transitory or a permanent way. This situation can motive the doubt at the diagnostic, even though it exists in a little patients' group. In this work there are revised its causes and mechanisms.
