Abstract

The lung is an extremely common site for metastasis from extrathoracic tumors. But intraluminal bronchial metastasis, especially from the thyroid medullary carcinoma is unusual lesions. A 41-year-old male patient complained of dry cough for 5 month. The patient had underwent total thyroidectomy with the right modified radical neck dissection because of thyroid medullary carcinoma 14 months ago. The chest X-ray showed both hilar prominancy. The chest computerized tomographic scan revealed endobronchial lesion in the right main bronchus and the left upper lobe bronchus with multiple lymphadenopathies in the subcarina and the left hilum. The bronchoscopy disclosed polypoid mass and multiple small nodules on the bronchial wall. We confirmed endobronchial metastasis from the thyroid medullary carcinoma by bronchoscopic biopsy.
