Neonatal lupus erythematosus with recurrent pancytopenia: a case report.

Neonatal lupus erythematosus is an immune-mediated disease associated with the transplacental passage of maternal autoantibodies, primarily anti-Ro (SS-A) and anti-La (SS-B). The major clinical manifestations are isolated congenital heart block and cutaneous lupus lesions. Other symptoms include hematologic and hepatic abnormalities. We report a male neonate, born to a mother with Sjögren's syndrome, who experienced cutaneous lupus lesions and 2 episodes of pancytopenia. Both anti-Ro and anti-La antibodies were positive in infant and mother.
