To the Editor.—
Recently we observed a case of neonatal lupus erythematosus (NLE) that has prompted us to reemphasize the need for testing for anti-SSA/Ro antibody in all cases of annular skin eruptions in infancy. We suspect that several previous reports of annular skin eruptions in infants were actually cases of NLE, but at the time they were reported, the specific marker for this disorder, the anti-SSA/Ro antibody, had not yet been elucidated.

He also had a 2-mm red papule over the right temple (which subsequently enlarged to an annular lesion) and a 5-mm annular lesion on the right thigh. The remainder of
