Abstract:
Anisakiasis refers to a parasitic infestation by nematode larvae that belong to the subfamily Anisakinae. Colonic anisakiasis is very rare, and it is hard to diagnose compared with gastric anisakiasis. Endoscopic or radiologic findings, history of raw fish intake and ELISA test might be helpful, however, exploratory operations were needed to confirm the diagosis in the many cases of colonic anisakiasis. Colonoscopy and endoscopic ultrasonography showed a submucosal tumor in the ascending colon in a 47-year-old woman who complained of right upper quadrant abdominal pain. Right hemicolectomy was performed to diagnose and cure the lesion. Pathologic examination revealed some destructed cuticle of a parasite and dense eosinophilic abscess showing central necrosis. She had a history of raw squid intake recently. We report a case of submucosal tumor in the ascending colon probably caused by Anisakis.
