We present a case of esophageal anisakiasis in a 61-year-old male who experienced severe precordial pain and radiating discomfort to the neck after consuming raw fish sashimi. Upper gastrointestinal endoscopy revealed the presence of a larva in the upper esophagus. On the basis of anatomo-morphological features, the worm was provisionally identified as Anisakis sp. and was easily extracted with forceps, which led to a prompt improvement in the patient\u2019s symptoms. This case highlights the importance of considering anisakiasis as a differential diagnosis in patients with gastrointestinal symptoms and a history of consuming raw fish.<\/jats:p>","DOI":"10.3390\/medicina59101888","type":"journal-article","created":{"date-parts":[[2023,10,23]],"date-time":"2023-10-23T10:32:24Z","timestamp":1698057144000},"page":"1888","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Anisakiasis in the Upper Esophagus: A Case Report"],"prefix":"10.3390","volume":"59","author":[{"given":"Eiji","family":"Kamba","sequence":"first","affiliation":[{"name":"Department of Gastroenterology, Juntendo University School of Medicine, Tokyo 113-842, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7419-589X","authenticated-orcid":false,"given":"Takashi","family":"Murakami","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Juntendo University School of Medicine, Tokyo 113-842, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5370-1009","authenticated-orcid":false,"given":"Hiroya","family":"Ueyama","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Juntendo University School of Medicine, Tokyo 113-842, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3558-7123","authenticated-orcid":false,"given":"Tomoyoshi","family":"Shibuya","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Juntendo University School of Medicine, Tokyo 113-842, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9671-5585","authenticated-orcid":false,"given":"Mariko","family":"Hojo","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Juntendo University School of Medicine, Tokyo 113-842, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ken","family":"Yamaji","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine and Rheumatology, Juntendo University School of Medicine, Tokyo 113-842, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5979-4384","authenticated-orcid":false,"given":"Akihito","family":"Nagahara","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Juntendo University School of Medicine, Tokyo 113-842, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,23]]},"reference":[{"key":"ref_1","first-page":"E83","article-title":"Esophageal anisakiasis observed using magnifying endoscopy with narrow-band imaging","volume":"53","author":"Mannami","year":"2020","journal-title":"Endoscopy"},{"key":"ref_2","first-page":"97","article-title":"A nematode parasitic to herring, causing acute abdominal syndromes in man","volume":"12","author":"Kuipers","year":"1960","journal-title":"Trop.
