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($U_1RNP$) antibodies. Cases of $U_1RNP$ antibody-positive NLE have somewhat atypical cutaneous manifestation without cardiac or systemic abnormalities. We report a case of cutaneous NLE associated with $U_1RNP$ antibodies.
