A Case of Gastroesophageal Amyloidosis with Upper Gastrointestinal Bleeding in a Patient with Multiple Myeloma / 대한소화기내시경학회지

ABSTRACT

Amyloidoses are disorders for which homogeneous amorphous fibrillar proteins accumulate in multiple organs. These diseases are classified into systemic and localized disease by their extent, the primary disease and their association with multiple myeloma, and the secondary and familial disease are classified by their association with the underlying diseases. Amyloidoses can develop in association with multiple myeloma, but only rare cases have been reported on that involve the gastroesophageal tract. Amyloidosis can involve the kidney, heart, liver, skin, gastrointestinal tract and nervous system, and they can involve the small intestine, duodenum, stomach, colon, rectum and esophagus when there is disease of the gastrointestinal tract. We may overlook gastrointestinal involvement of amyloidoses if there are few symptoms and laboratory abnormalities because of the diverse clinical courses and features. Amyloidoses can manifest abdominal pain, diarrhea, vomiting and perforation, but gastrointestinal hemorrhages are rare. We report here on a case of gastroesophageal amyloidosis with upper gastrointestinal hemorrhage and paralytic ileus due to multiple myeloma.
