Local Recurrence due to Needle Tract Seeding after Endoscopic Ultrasound-Guided Fine-Needle Aspiration for Pancreatic Tail Cancer: A Case Report.

ABSTRACT:

Introduction

Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is an essential diagnostic tool for pancreatic tumors, but rare complications such as needle tract seeding (NTS) may cause local recurrence.

Case presentation

A 79-year-old man with a history of right hemicolectomy for colon cancer presented during follow-up in 2020 with a 16-mm pancreatic tail mass. He was asymptomatic, and laboratory findings including carcinoembryonic antigen and carbohydrate antigen 19-9 were normal. EUS-FNA confirmed adenocarcinoma (cT3N0M0, stage IIA), and after neoadjuvant chemotherapy, laparoscopic distal pancreatectomy was performed. No recurrence was observed until 2022, when elevated tumor markers and fluorodeoxyglucose positron emission tomography/computed tomography revea
