Forward-Viewing Endoscopic Ultrasound-Guided Fine-Needle Biopsy for a Hypopharyngeal Carcinoma Mimicking a Subepithelial Lesion: A Case Report.

ABSTRACT: Subepithelial lesions (SELs) of the head and neck have a low diagnostic yield with mucosal biopsy and carry a bleeding risk. Among endoscopic ultrasound-tissue acquisition (EUS-TA) techniques, fine-needle biopsy (FNB) provides higher specimen adequacy and diagnostic accuracy than fine-needle aspiration (FNA). A forward-viewing curved linear-array echoendoscope (FV-EUS) is useful for mobile lesions and those in narrow spaces that are difficult to puncture with conventional oblique-viewing EUS (OV-EUS), but FV-EUS-guided EUS-FNB has not been reported for head and neck lesions. We report a 72-year-old man in whom a lesion at the esophageal inlet was not apparent on initial upper gastrointestinal endoscopy performed with a small-caliber endoscope. Stenosis was subsequently noted at the time of
