False-positive transcarinal needle aspirate in the evaluation of bronchogenic carcinoma.

Advances in the staging of regional mediastinal lymph node metastases from lung carcinoma include transcarinal needle aspiration. However, since most clinicians feel that documented tumor involvement of subcarinal nodes is a strong contraindication to aggressive surgical resection, a falsely positive carinal aspirate could deny a patient potentially curative resectional surgery. Herein, we present a case of a falsely positive transcarinal needle aspirate in which resectional surgery was carried out with a subsequent 34-month disease-free state.
