This vasculitis is usually seen idiopathic in patients with a long history of asthma; oral steroids using steroid inhalers, vaccination and desensitization might be triggering factors. Drugs such as leukotriene receptor antagonists (LTRAS), penicillin, sulphonamides, anticonvulsants and thiazides have also been

By presenting the cases in this article, the authors suggest that some cases of CSS may be partially or totally suppressed by corticosteroid therapy of asthma for long periods and replacing oral steroid by inhaler will reveal a pathologic condition of CSS, called frustes CSS forms. We report three subjects with asthma who had been receiving previously multiple corticosteroid courses for control, but when systemic corticosteroids were discontinued or switched over to steroid inhaler, the patients developed a similar syndrome.
