گزارش مورد: مورد نادر فیستول تراکئوازوفاژیال اکتسابی ثانویه به سرطان حنجره

Acquired Tracheoesophageal fistula(TEF) is a rare complication that can occur due to different reasons. One of the most common causes is a malignant lesion close to the region (۵۰%). Although The primary tumor usually originates in the esophagus, the lung and tracheal, in rare cases, can be from the larynx. In our case, a ۶۸-year-old man, a known case of cured laryngeal cancer for ۱۵ years, with complaints of increased dyspnea and productive cough, was presented to the hospital. The patient was recently hospitalized for the same condition which was finally treated for lung infection. The patient experienced the same condition and had treatment for pneumonia at this time again. Due to dysphagia and recent weight loss, a Barium swallow was performed. It showed a Tracheobronchial tree, which confirmed the possible TEF. The patient was referred to a specialized hospital to insert a stent in the esophagus. However, due to the patient's severe condition, the patient did not survive. TEF, a complication of laryngeal cancer, is rare but can be fatal. Any findings for aspiration pneumonia in such patients (e.g., sudden dyspnea) can be an alarm sign of TEF.
