Almost all cases of gastric anisakiasis with acute symptoms have been easily cured by endoscopic removal of the worm which penetrated the stomach wall without the need for surgical operation [1–8]. Therefore, pathological studies  of the stomach during the acute phase of gastric anisakiasis are very rare. In animal experiments, the main lesion of this disease is found in the submucosal part of the stomach, causing severe edema and eosinophilic cell infiltration around the penetrating worm . In this chapter, biopsy findings of this disease are presented.
