We describe an 8-year-old girl with a prolonged history of cough and eosinophilia that initially was labeled as pulmonary tuberculosis, but after complementary assays, associated with skin biopsy, eosinophilic fibrinoid vasculitis, CSS was eventually diagnosed. In this case, due to her young age and more prevalence of infectious lung diseases in our area, there was a few months delay for correct diagnosis and treatment. After meeting the CSS criteria the appropriate treatment was started and her condition improved. https://ijaai.tums.ac.ir/index.php/ijaai/article/view/67 https://ijaai.tums.ac.ir/index.php/ijaai/article/download/67/67
