A Case with Gastric Anisakiasis Presented with a Submucosal Tumor / 대한소화기내시경학회지

ABSTRACT

Anisakiasis is a parasitic infestation caused by nematode larvae belonging to the subfamily Anisakinae when a raw or inadequately cooked fish is ingested. The clinical symtoms are severe cramping abdominal pain, nausea, vomiting, epigastric fulling sensation, but hematemesis or melena is very rare. We report a case of a 60-year-old male patient who developed melena one day after eating raw sea-fish. An esophagogastroduodenoscopy revealed a submucosal tumor with an ulceration located in the gastric fundus and subsequently an explolaparotomy and mass excision was performed due to massive bleeding. An anisakis larva was found in the resected mass, which was thought to be gastric anisakiasis.
