[A case of localized AL-type amyloidosis of the stomach].
A 78-year-old woman was admitted to our hospital for treatment of liver cirrhosis and an esophageal varix. Endoscopy revealed a protruding nodular lesion with a transparent smooth surface proximal to the pylorus, which was accompanied by a partly yellow-whitish spot. A depressed lesion with an even edge was found. Histologically, the protruding lesion and depressed lesion showed amyloid deposits, mainly in the mucosal layer. The lesions were found to correspond to AL type amyloidosis by immunochemical analysis. General examination showed no other amyloid deposits. Thus, we diagnosed localized amyloidosis of the stomach.
