[Pseudotumoral gastric amyloidosis]

Localized gastric amyloidosis is rare. It should be considered in differentiation of gastric tumors, in which biopsy is the only means to confirm the diagnosis.

A 56-year old male patient presented dysphagia and vomiting. A plastic linitis was suggested by endoscopic ultrasonography. Total gastrectomy and clearance of perigastric lymph nodes were performed. The postoperative pathological diagnosis determined the lesion to be localized gastric amyloidosis and no malignant tumor was found. No sign of recurrence has been found one year after surgical resection.

Currently, surgical resection of pathological tissue and circumambient lymph nodes may be a preferable therapeutic strategy for the localized amyloidosis to prevent possible complications.
