Biopsy of an involved area of the skin shows a neutrophilic infiltrate without evidence of vasculitis or hemorrhage.

Plaquenil is also used to treat symptoms of rheumatoid arthritis and discoid or systemic lupus erythematosus. Hydroxychloroquine should be discontinued if ocular toxicity is suspected and patient should be closely observed given that retinal changes and visual disturbances may progress even after cessation of therapy. Hepatic disease or alcoholism Schnitzler syndrome or Schnitzler's syndrome is a rare disease characterised by onset around middle age of chronic hives urticaria and periodic fever, bone pain and joint pain sometimes with joint inflammation, weight loss, malaise, fatigue, swollen lymph glands and enlarged spleen and liver. Recognition of this syndrome is critical since it is highly responsive to anakinra. Although the etiology of the syndrome is unknown, current evidence suggests this is an autoinflammatory syndrome.

Schnitzler Syndrome - NORD National Organization for Rare.. Schnitzler syndrome - Wikipedia. The hypocomplementemic urticarial-vasculitis syndrome.. Schnitzler syndrome is characterized by chronic, nonpruritic urticaria in association with recurrent fever, bone pain, arthralgia or arthritis, and a monoclonal immunoglobulin M IgM gammopathy in a concentration of usually less than 10 g/L. Approximately 10-15% of patients eventually develop a lymphoproliferative disorder, such as lymphopla. The only other diagnostic test I might consider in very severe refractory chronic urticaria is a SPEP or IFE to eval for monoclonal gammopathy and exclude Schnitzler syndrome, though these patients usually have additional systemic symptoms and other serologic markers of systemic inflammation. Schnitzler's syndrome is characterized by recurrent urticarial rash and monoclonal gammopathy, associated with clinical and biological signs of inflammation and a long‐term risk of AA amyloidosis and overt lymphoproliferation.
