[Neonatal lupus erythematosus, a clinical case].

Unlabelled: Neonatal lupus erythematosus (NLE) is a very rare autoimmune disease, occurring in neonates born to mothers who present auto-antibodies to cytoplasmic antigens of Sjögren's syndrome. In most cases, the clinical course is benign toward spontaneous resolution, but there is a group of patients who develop severe involvement of the cardiac conduction system, therefore, early detection is critical.

Objective: To describe a clinical case of neonatal lupus erythematosus emphasizing the importance of timely diagnosis in the patient and the mother.
