Symptoms are usually mild, but in the setting of impaired host immunity, severe and disseminated illnesses may occur. The present report describes a male patient with a history of asthma and corticosteroid therapy, now presented with dyspnea and abdominal pain. Examinations show Strongyloides stercoralis larvae in Bronchoalveolar lavage fluid specimens. The patients who have undergone immunosuppressive therapy are highly indicated for Strongyloides stercoralis screening which prevents hyperinflation in endemic areas. https://acta.tums.ac.ir/index.php/acta/article/view/8690
