ABSTRACT
Neonatal lupus erythematosus is a very rare disease, clinically characterized by skin lesions that resemble those of subacute or discoid lupus erythematosus and/or congenital heart block. Generally, when patients have skin manifestations, they have no cardiac defects and vice-versa; however, in 10% of cases these manifestations may coexist. Other findings may include hematologic, hepatic and neurological abnormalities. This condition is caused by the transplacental passage of maternal autoantibodies against Ro (95%), La and, less frequently, U1-ribonucleoprotein (U1-RNP). The present case report describes four patients with clinical, histopathological and immunological findings compatible with neonatal lupus erythematosus, their treatment and progress.

El lupus eritematoso neonatal es una enfermedad poco frecuente, caracterizada clínica mente por alteraciones cutáneas semejantes al lupus subagudo o discoide y/o bloqueo cardíaco congénito. Generalmente, cuando los pacientes presentan manifestaciones cutáneas, no tienen anormalidades cardiológicas y viceversa, aunque en un 10 por ciento de los casos ambas manifestaciones pueden coexistir. Puede acompañarse también de alteraciones hematológicas, hepáticas y neurológicas. Es causado por el pasaje trasplacentario de anticuerpos maternos anti Ro (95 por ciento), anti La y menos frecuentemente anti U1RNP. Presentamos cuatro pacientes con hallazgos clínicos, histopatológicos e inmunológicos compatibles con lupus eritematoso neonatal, su tratamiento y evolución.
