Polycarbophil calcium (Polyful; Mylan, Tokyo, Japan) is a stool stabilizer that absorbs liquid and swells to form a soft, bulky mass. A 75-year-old woman experienced sore throat and difficulty breathing immediately after taking the drug. Chest computed tomography showed a foreign body in the right intermediate bronchus. Bronchoscopy showed a white mass blocking the right intermediate bronchus. Since the mass was very fragile, we performed suctioning while breaking up the mass with a suction tube. The mass consisted of polycarbophil calcium. Since aspirated polycarbophil calcium swells and can obstruct bronchi, complete removal is crucial.
