Background.- Churg-Strauss syndrome is a rare disorder, and is characterized by association of bronchial asthma with disseminated vasculitis, eosinophilia, and extravascular granulomas.
Observation.- We describe a 35 year old female patient in whom necrotising cutaneous lesions, arthralgia, and symptoms due to multiple peripheral nerve involvement developed during the treatment of bronchial asthma. The diagnosis of Churg-Strauss syndrome was confirmed histopathologically. The clinical and laboratory features of the syndrome, differential diagnosis, and treatment options are discussed.
