Churg Strauss Syndrome After Polypectomy in Asthmatic and Allergic Patients

churg strauss syndrome (css) is a form of primary vasculitis that is characterized by severe eosinophilia and often granulomatous inflammation as well as history of asthma or allergy. previously, the association between cysteinyl leukotrien receptor antagonists (ltras), corticosteroid withdrawal or a sudden change in its used method and css had been established. we report three cases that have been referred because of dyspnea, wheezing and cough with a history of allergic rhinitis and nasal polypectomy. after polypectomy, disseminated skin purpuric rashes appeared on their forelegs, abdomen and all of them had experienced neuropathic signs in their extremities. clinical findings, marked eosinophilia in blood and skin biopsies finally led to the diagnosis of css. the patients have been free of symptoms after receiving prednisolone; routine examinations and blood tests have rended regular results. here, we report a probable occurrence of an association between nasal polypectomy and css on the basis of our findings. further, extended researches are required to establish this correlation.
