A case of hitherto unreported intestinal anisakiasis with massive gastrointestinal hemorrhage as the chief complaint is reported. A 37-year-old male presented with melena as the chief complaint, and fell into a state of shock while endoscopy and other procedures failed to make a diagnosis. Abdominal angiography revealed an area of hypervascularity at the proximal end of the jeunum. An emergency operation was carried out and close inspection revealed a mass at the proximal end of the jeiunum, Which was thought to be the bleeding point and was duly resected. Histological section revealed a submucosal granuloma with remnants of the Anisakis larvae with eosinophilic infiltration in the central abscess, hence the above diagnosis. The high titer of anti-anisakis antibody supported the diagnosis.
