[Acute Guillain-Barré-like polyradiculoneuritis revealing acute systemic lupus erythematosus: two case studies and review of the literature].

The involvement of the peripheral nervous system in systemic lupus erythematosus (SLE) is rare and is dominated by distal symmetric axonal polyneuropathy and multiple mononeuropathy. It usually occurs in late course of the disease. Acute polyradiculoneuropathy of Guillain-Barré syndrome type is very rare and can frequently constitute the first symptom of systemic lupus.
