[Gastric carcinoid tumor in pernicious anemia].

A case of a 39 year-old woman with recently diagnosed PA and a GCT is reported. Recent surveys have shown that GCTs occur far more frequently in patients with chronic atrophic gastritis type A (+/- PA) than previously noted. This may be due to an improved endoscopic technique and the use of specific immunostains, such as chromogranin A, which in our case was essential in avoiding the diagnostic pitfall of an adenocarcinoma. The pathogenesis and the management of type-1 GCT are discussed.
