A 58-year-old woman was referred to our hospital because of an abnormality in the gastric corpus detected during mass screening. Radiological and endoscopic examinations of the gastrointestinal tract showed a localized elevated lesion covered with coarse mucosa on the lesser curvature in the corpus. Histological examination of the biopsy specimens revealed amyloid deposits of AL type in the mucosal layer. No other organs were affected by amyloidosis. Relying on these findings we diagnosed the disorder as AL amyloidosis localized to the stomach. There has been no obvious progression during the six years since the first medical examination.
