Espectro clínico del lupus eritematoso neonatal cutáneo

In our series, NLE was three times more frequent in males. Involvement of sun-exposed areas, such as the face with annular lesions was the most common finding. We found one case of NLE with cutaneous involvement and persistent ductus arteriosus. Anti-Ro antibodies were found in all cases and skin eruptions cleared by 7 months of age, concurrent with the waning of the maternally derived antibodies. Four of the mothers were asymptomatic and unaware of their condition, emphasizing the importance of following up these patients due to the possibility of developing an autoimmune disease.
