A rare case of gastrointestinal amyloidosis secondary to myeloma with predominant jejunal involvement.

Amyloidosis is a condition identified by the accumulation of abnormal proteins in various tissues and organs that eventually lead to impaired function. Systemic amyloidosis with gastrointestinal (GI) tract involvement is more common than localized GI amyloidosis, whereas predominant jejunal involvement is even more uncommon. We report a rare case of systemic amyloidosis with predominant jejunal involvement in a 76-year-old female who presented with lower abdominal bloating and lethargy.
