Abstract
-
Anisakiasis is a parasitic disease caused by ingestion of raw fish infected with anisakis larvae. The endoscopic features of the gastic mucosa are edema, ulceration and hemorrhage. Chronic gastric anisakiasis forming a submucosal tumor is rare. A 53-year old female was diagnosed with having a 1 cm sized gastric submucosal mass-like lesion by gastroscopy. Endoscopic ultrasonography showed an inhomogenous low echoic tumor with an irregular margin in the submucosal layer. The patient underwent an endoscopic submucosal dissection and band ligation. A serological assay with an enzyme-linked immunosorbent assay for an anisakiasis specific IgG antibody were positive. The pathological finding of the resected mass was centrally denatured larvae with eosinophilic abscess in the submucosal layer. We report a case of chronic gastric anisakiasis that presented as a gastric submucosal tumor that was removed by the endoscopic submucosal dissection method, with a review of the relevant literature.
