Abstract

Tracheal cancer is rare and accounts for approximately 0.03% of all malignancies. Because of atypical symptoms, tracheal cancer can be misdiagnosed as obstructive lung disease, or tumors of thyroid or lung. Among patients of previous head and neck cancer, other primary cancer may accompany which called “second primary cancer”. We report a case of patient with tracheal cancer 3 years after definite radiation therapy of laryngeal cancer with a review of related literatures.
