Churg-Strauss syndrome (CSS) is a very rare disease which combines the features of asthma, hypereosinophilia, multisystem necrotizing vasculitis and extravascular granuolma. To our knolwedge, there have been four reports in Korean journals, but none in dermatology journals. We report a 37-year-old male who had allergic rhinitis, pansinusitis, a history of atopic dermatitis, multiple prurigo-nodularis like skin lesions, non-fixed interstitial lung in-filtration, hypereosinophilia and subclinical asthma. Clinical and histopathological features of his skin lesions were nonspecific where perivascular lymphocytic infiltration and mild lymphocytic vasculitis were shown. The presence of a pituitary mass and proximal myopathy as op-posed to peripheral neuropathy have not been reported in previous reports of CSS. However, other features of our patient met the criteria of CSS.
