  • 1Department of Internal Medicine, Chung Goo Sung Sim General Hospital, Seoul, Korea.


Anisakiasis is an infection in humans caused by larval nematodes of the family Anisakidae and is encountered in people who eat inadequately prepared raw, salt-water fish or "sashimi". This clinical syndrome is characterized by severe cramping abdominal pain, nausea, and vomiting. Because Koreans like to eat raw fish, anisakiasis of the stomach has been reported occasionally, but the incidences of upper gastrointestinal bleeding caused by anisakiasis has been very rare. The present case is a 30 year-old male Admitted with an episode of hematemesis. A gastrofibroscopy revealed a mucosal laceration and the larva of Anisakis on the esophagogastric junction. We report one case of Mallory-Weiss Syndrome due to gastric Anisakis larva, confirmed by an endoscopy.
