[Juvenile gastric polyposis in a patient with antiphospholipid syndrome].

We report a case of juvenile gastric polyposis associated with antiphospholipid syndrome. A 42-year-old woman was admitted with a chief complain of fatigue. Six years earlier, antiphospholipid syndrome was diagnosed and treated with aspirin. Two years earlier, gastric polyps were endoscopically observed, the number and size of which subsequently increased. Juvenile gastric polyposis was diagnosed on the basis of the pathological features of the biopsy specimens. Bleeding was repeatedly identified from the polyposis. Total gastrectomy was performed because of worsening anemia and hypoalbuminemia.
