A first report of endoscopic ultrasound for the diagnosis of pancreatic amyloid deposition in immunoglobulin light chain (AL) amyloidosis (primary amyloidosis)

JOP. 2013 May 10;14(3):283-5. doi: 10.6092/1590-8577/1505.

Abstract

Context: Pancreatic involvement in systemic light chain (AL)-amyloidosis is exceedingly rare. Prior reports of endoscopic ultrasound (EUS) for the diagnosis of amyloidosis are also limited.

Case report: We report the first description of EUS-guided fine needle aspiration (FNA) for the diagnosis of primary AL-amyloidosis involving the pancreas.

Conclusion: EUS-FNA can be effectively utilized for the characterization and cytologic diagnosis of pancreatic amyloidosis and potentially other accessible extraluminal amyloid deposits.
