Malignant bronchosubcutaneous fistula presenting as subcutaneous emphysema

Abstract

A bronchosubcutaneous fistula is a communication between the subcutaneous tissues, the pleural cavity, and the bronchial system. It is a rare manifestation of primary pulmonary disease. The authors present a very unusual case of bronchosubcutaneous fistula that presented as subcutaneous emphysema after palliative radiation therapy for primary carcinoma of the lung.
