title: An anisakis larva attached to early gastric cancer: report of a case.
abstract: Gastrointestinal anisakidosis is a nematode infection caused by the ingestion of larvae-infected raw or undercooked fish. The Japanese like to eat raw or undercooked fish, so gastric anisakiasis is a common disease in Japan. However, reports of anisakiasis with gastrointestinal cancer are rare. A 63-year-old Japanese male was diagnosed with a small early gastric cancerous lesion associated with gastric anisakiasis. From our experience and based on a review of the literature, the attachment of an anisakis larva to early gastric cancer is not considered accidental.
