RESULTS: Nineteen patients with systemic AL amyloidosis of the luminal gastrointestinal tract were identified. Gastrointestinal symptoms or signs related to amyloid involvement were noted in 95% of patients; abdominal pain, change in bowel habits, overt gastrointestinal bleeding, and complaints related to altered motility were the predominant presentations. Endoscopic abnormalities were found in nearly three fourths of patients, including ulcerations and submucosal hematomas. When gastrointestinal bleeding was the presenting symptom, submucosal hematomas were a common finding during endoscopic evaluation.

CONCLUSIONS: AL type amyloidosis of the luminal gastrointestinal tract is a rare disease that presents with common, nonspecific complaints. The endoscopic detection of a submucosal hematoma in the setting of gastrointestinal bleeding in patients with plasma cell dyscrasias should raise suspicion for the disease.
