[Schnitzler's syndrome with urticaria vasculitis].

Schnitzler's syndrome is a rare disease characterized by the association of chronic urticaria, intermittent fever, bone pain, arthritis, and monoclonal IgM gammopathy. It was first described by the French dermatologist Liliane Schnitzler in 1974. Because of the variety of clinical signs, the syndrome is of concern to doctors of different specialties and is of special interest to internists, rheumatologists, hematologists and dermatologists. Up to now, treatment was often difficult and disappointing. Interleukin-1 receptor antagonists offer a new therapeutic option.
