Dysphagia in patients with lung cancer is usually due to direct invasion from bronchogenic carcinomas or nodal localizations, while metastases from distant lung neoplasms are considered rare. We report a case of a smooth esophageal narrowing secondary to intramural metastasis from pulmonary adenocarcinoma in a patient with no previous history of neoplasia. Since standard linear echoendoscope could not overpass the malignant stricture, we obtained a histological diagnosis by fine-needle aspiration biopsy using an echobronchoscope (EBUS), due to its lower diameter. The EBUS scope represents a valuable tool to obtain cytological specimens in patients with esophageal strictures.
