Abstract
|
|
|
|
Amyloidosis is characterized by extracellular deposition of insoluble protein fibrils that stain with Congo red application and appear apple green under polarized light. The presenting symptoms result from the involvement of many affected, nonspecific and generalized organ systems. Our patient was an 80-year-old woman with no medical history. She presented with a 2-week history of nausea and vomiting. An esophagogastroduodenoscopy showed erythematous and edematous mucosa on the antrum with pyloric stenosis. Histopathologic examination of the biopsy specimen showed the deposition of amorphous, homogeneous, and acidophilic material in the gastric mucosa. Amyloidal protein was proven by positive Congo red stain. A serum and urine immunfixation electrophoresis showed lambda light chain band. She developed symptoms of repeated greenish color vomiting. A follow-up esophagogastroduodenoscopy showed progressed antral obstruction. However, she refused further evaluation and treatment and was managed conservatively. She later died of disease progression after 34 hospital days.
