Background. Chlorine-based bleaching agents are commonly used at home for laundry and cleaning tasks. The chlorine and synthetic substance produced by various factors in bleach affect the mucous membrane of the eyes, pharynx, and respiratory tract. Case. We report a case of a 38-year-old man suspected of having interstitial pneumonia and referred to our department. He had been soaking tableware in undiluted chlorine-based bleach while sleeping in an adjacent room. He had woken up with a sore throat and cough, and gradually developed dyspnea. Flexible bronchoscopy was performed for differential diagnosis. The mucosa was redness and swollen. Bronchoalveolar lavage showed that the neutrophil count had increased to 32.0%. Transbronchial lung biopsy showed focal alveolar epithelial damage. Considering all results, chemical pneumonitis due to chlorine-based bleach was diagnosed. Oxygen and steroids were administered resulting in the remission of symptoms, and the patient was discharged. Conclusion. Misuse of chlorine-based bleach can cause chemical pneumonitis and requires careful treatment.
