A First Report of Endoscopic Ultrasound for the Diagnosis of Pancreatic Amyloid Deposition in Immunoglobulin Light Chain (AL) Amyloidosis (Primary Amyloidosis)
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.
