title: Seeding of malignant cells into the needle track after lung and pleural biopsy.
abstract: Transthoracic needle biopsy is frequently performed for the diagnosis of pulmonary and pleural disease. Seeding of malignant cells is a potential complication but is extremely uncommon. We report the second patient with malignant seeding after fine-needle aspiration biopsy of a bronchogenic carcinoma. We also report a patient with seeding of bronchogenic carcinoma after a pleural biopsy. Because seeding is a rare complication, it does not affect the indications for biopsy.
