Endoscopic ultrasound-guided pancreas biopsy in the hands of a chest physician.

This is the first paper to report sampling of pancreatic lesions by EUS-B-FNA. A 76 year old patient suspected of primary lung cancer presented with a 36 × 24 mm lesion in the pancreas. Thoracentesis showed malignant cells suggestive of mucinous adenocarcinoma, but immunohistochemistry was inconclusive.
