Churg-Strauss Syndrome was described in 1951 and it is characterized by asthma, fever, hypereosinophilia and vasculitis. In 1990, following the discussion of several proposals for its classification, the American College of Rheumatology established its diagnostic criteria. A 55 year-old female patient was seen recently at the Military Hospital in Bogota, Colombia, with leucocytoclastic vasculitis, wheezing, pulmonary infiltrates and hypereosinophilia, who met all the criteria to be classified as a Churg-Strauss patient.
