A Rare Case of Gastrointestinal Amyloidosis Presenting as Dysphagia

A 74-year-old male with an unintentional 20-pound weight loss over the past year presented with new-onset dysphagia to solid foods. Esophagogastroduodenoscopy showed a subtle stricture with ill-defined scar tissue-like findings in the distal esophagus and erosions in the antrum of the stomach without masses. Pathologic findings showed the presence of amyloidosis involving the proximal and distal esophagus, as well as gastric mucosa with chronic inflammation and reactive epithelial changes. We present a rare case of dysphagia as the initial presentation of gastrointestinal amyloidosis.
