Neonatal lupus erythematosus: An acquired autoimmune disorder and its cutaneous manifestations

Neonatal lupus erythematosus is an uncommon transplacentally acquired autoimmune disorder. The most common clinical manifestations are skin rash, congenital atrioventricular block, thrombocytopenia, leukopenia, anemia, and hepatosplenomegaly. Usually, the skin rash resembles subacute cutaneous lupus, but diferent forms of rash have been reported in neonatal lupus erythematosus and some are rare forms. NLE should be suspected in babies with atypical skin lesions, even if present at birth.
