ABSTRACT
Neonatal lupus erythematosus(NLE) is a distinct subset of lupus characterized by cutaneous findings, cardiac conduction defects, hepatic or hematologic abnormalities. These manifestations are associated with the presence of maternal auto-antibodies such as anti-SSA/Ro, anti-SSB/La, and rarely anti- RNP(U1RNP) antibodies. Cases of U1RNP antibody-positive NLE have somewhat atypical cutaneous manifestation without cardiac or systemic abnormalities. We report a case of cutaneous NLE associated with U1RNP antibodies.

AntibodiesABSTRACT
Neonatal lupus erythematosus(NLE) is a rare syndrome occuring in neonates with transplacentally acquired maternal autoantibodies, in particular anti-Ro, anti-La or anti-U1RNP. We report a case of NLE in a 50-day-old male neonate born to a systemic lupus erythematosus-mother with anti-U1RNP autoantibodies; on a review, there have been 8 cases of NLE reported in Korean literature.
