Late Onset Chemo/Radiation Induced Tracheoesophageal Fistula in Squamous Cell Cancer of the Lung.

We report a 72-year-old male with past medical history of stage IV squamous lung cancer treated with radiation therapy and chemotherapy with gemcitabine/carboplatin. One year later, he presented with hemoptysis treated with another session of palliative radiotherapy. Two weeks later, patient developed aspiration pneumonia and further workup showed trachea-esophageal fistula documented by barium swallow. This case shows a rare complication of chemotherapy and radiation therapy on the setting of primary lung cancer.
