Esophageal Metastatic Adenocarcinoma Diagnosed with Endoscopic Ultrasound

Abstract

Metastasis to the esophagus from a distant primary cancer is a rare manifestation in a patient with a history of oncological disease presenting with obstructive upper gastrointestinal symptoms. Computed tomography of the thorax or esophagogastroduodenoscopy can be non-diagnostic as the disease tends to be submucosal. In such a situation, endoscopic ultrasound (EUS) with fine needle aspiration (FNA) can be directed to characterize and sample the submucosal esophageal lesion. We present a case series of metastatic esophageal strictures diagnosed with EUS and FNA.
