A Case of Neonatal Lupus Erythematosus / 대한피부과학회지

ABSTRACT

Neonatal lupus erythematosus is a rare disorder caused by the transplacental passage of maternal autoantibodies, which result in congenital heart block or cutaneous eruptions similar to lesions of subacute cutaneous lupus erythematosus. We report a case of a 29 day-old-male infant who presented with multiple, targetoid lesions with an edematous margin on the scalp, face, neck, and extremities. His serological tests revealed high titers of anti-La/SSB and antinuclear antibodies. His healthy mother also showed the same high titer of antibodies. Yet, the anti-Ro/SSA antibodies were negative in both of them.
