Gastroparesis in a Patient with Gastric AL Amyloidosis

Systemic amyloidosis is a group of complex disorders characterized by the extracellular deposition of nonbranching fibrils in various tissues, ultimately leading to a variety of clinical presentations including isolated or multiorgan dysfunction. Amyloid involvement of the gastrointestinal tract is common depending on the subtype of this disease; light chain primary amyloidosis (AL) and secondary amyloidosis (AA) affect the gastrointestinal tract in unique ways due to differing pathophysiology. A case is reported of gastroparesis associated with AL amyloidosis diagnosed by esophagogastroduodenoscopy and study of gastric emptying, then subsequently confirmed by Congo red staining performed on endoscopic biopsies.Case Rep Gastroenterol 2018;12:317 –321
