Lymph node manifestations of limited Churg-Strauss syndrome.

Churg-Strauss syndrome is a systemic vasculitis characterized by asthma, tissue and blood eosinophilia, and granulomatous vasculitis. Lymph node involvement as part of systemic disease or as the primary site of involvement is rare. We report a single case of primary (isolated) nodal Churg-Strauss syndrome occurring in an 11-year-old boy with asthma, fever, night sweats, and cervical adenopathy. The clinical diagnosis was lymphoma. The unusual presentation of Churg-Strauss syndrome limited to lymph nodes is important to recognize and diagnose correctly because the administration of steroid therapy is associated with a favorable outcome.
