Abstract

Anisakiasis of the gastrointestinal tract is usually caused by the ingestion of raw marine fish infested with Anisakis larvae. A majority of cases present as gastric and intestinal anisakiasis. Anisakiasis of colon is rare and asymptomatic colon anisakiasis has a particularly low incidence. A 45-year-old man received colonoscopy that revealed a 1.0 cm sized whitish linear larva penetrating the mucosa of the cecum and it was removed by colonscopy. He had no complaint before the colonoscopy. A 52-year-old man complained of right upper quadrant abdominal pain with weight loss for one month. Colonoscopy revealed a 1.5 cm sized whitish linear larva penetrating the mucosa of the distal part of ascending colon. Abdominal pain and weight loss were improved by colonoscopic removal of larva.
