[A case of gastrointestinal AL amyloisosis requiring emergency surgery].
A 69-year-old man tarry stools received emergency endoscopy. Which revealed a solitary submucosal tumor about 15mm in diameter with a central ulcer, exhibiting woozing bleeding in the duodenal second portion. Endoscopic hemostasis was unsuccessful so emergency surgery was performed. Histological examination revealed amyloid with A-lambda immunoreactivity. Usually, this type of amyloidosis appears multiple submucosal masses. However this case presented as a single nodule at initial examination. We should keep in mind the potential of encountering this atypical form of amyloidosis.
