Endobronchial ultrasound staging of thyroid lesion in small cell lung carcinoma.

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has proven its utility in the mediastinal staging of lung cancer. Its use in the evaluation of thyroid lesions has not previously been described. We report the safe and effective use of EBUS-TBNA to evaluate a thyroid lesion in a patient with suspected lung cancer at the time of diagnostic bronchoscopy. Use of this method in the evaluation of thyroid lesions may be considered in patients with coexistent mediastinal or hilar lesions, or for lesions not accessible to a percutaneous approach.
