A 26-year old female suffered from dyspnea immediately after inhalation of a strong acid by mistake during a chemical experiment, and was admitted to a life-saving center. The acid was trifluoromethane sulfonic acid. Intratracheal intubation was performed promptly to prevent chemical bronchitis. When the tube was removed 3 days later, she didn't complain of dyspnea any more, although sight cough remained. She was discharged 12 days after the admission. After one and a half month after the discharge, dispnea took place again. She was referred to our institute because a large mass was found in her larynx by a doctor. The tumor originated from the right vocal fold was resected microsurgically. The histopathological examination revealed that the tumor was a nonspecific granuloma. No recurrence has been observed after the surgery for 4 months. The inhalation of acid, the intratracheal intubation, and sustaining cough were considered to be the cause of the laryngeal granuloma of this patient.
