Eosinophilic enteritis is characterized by massive infiltration of eosinophil throughout the entire or each layer of intestinal wall with marked submucosal edema. The etiology of this disease is not clear until now, and parasite infestation should be considered as a cause of eosinophilic enteritis like this case. We experienced a case of eosinophilic enteritis manifested by intermittent periumbilical pain and bloody ascites. After partial resection of ileum, we confirmed the eosinophilic abscess from Anisakis infestation and successfully treated this patient without sequalae and report it with literatures review.

Larval anisakids found in the yellow corvina (Pseudosciaena manchurica), a marine fish caught in the Yellow Sea, were classified by their morphological types. Total 1,068 anisakid larvae were collected from 30 fish examined, with the average number per fish of 35.6. They were classified into Anisakis type I larvae of Berland (859 in number, 80.4%), Contracaecum type A of Koyama et al. (13, 1.2%), Contracaecum type C'(new type) (55, 5.1%), Contracaecum type D of Koyama et al.(18, 1.7%), Contracaecum type D'(new type) (77, 7.2%), Contracaecum type V of Yamaguti(3, 0.28%), Raphidascaris sp. of Koyama et al. (1, 0.09%) and unidentified (42, 3.9%). Contracaecum type C' and D' were considered new in the literature.

Authors experienced a case of human infection with Anisakis sp. in left tonsil. The case was 27 year Korean female who visited Department of Otolaryngology, Severance Hospital with the chief complaints of swollowing difficulty, and the sensation of a foreign body in the throat, on November 20th 1968. Physical examination of the oral cavity revealed that both palatin tonsil were chronically enlarged. A larval worm was found in crypt of the upper portion of the left palatin tonsil. Chief complaints of the patient was improved after removal of it by forceps. The greyish white living worm was fixed in lactophenol solution for morphological study. The worm measured 36 mm in length by 0.6 mm in width, 2.4 mm in esophageal length, 1.4 mm in ventricule, 0.1 mm in tail length, and 0.025 mm in caudal spine length, respectively and histological study was carried out from the serial section of the larva which was stained with hematoxylin eosin. Authors identified that the larva was Anisakis species.

Anisakiasis is a disease caused by human infection by the Anisakis larvae, a marine nematode found in raw or undercooked fish. Most of anisakiasis are found in gastric or intestinal mucosa, but Anisakiasis in the oral cavity is rare. So, we elaborate on it in the present report with a review of literatures. This is the first report about anisakiasis of oral cavity in the recent literatures in Korea.

The infection status of anisakid larvae was examined in 290 marine fish of 25 species and in 108 cephalopods of 3 species purchased in Bayuquan region, Yingko city nearby the coast of the Bohai Sea from may to August 1992. A total of 7,327 larvae were collected from 156 fish of 19 species and 8 squids of one species. The 3rd-stage larvae of Anisakis simplex were collected from 121 fish (63.4%) of 15 species (N = 191) and from 8 squids (14.8%) of one species (N = 54), and they were total, 5,992 (81.8%). Out of remaining 1,335 larvae, 154 (2.1%) were classified as Thynnascaris type B from 23 fish of 4 species, 1,013 (13.8%) as Thynnascaris type C from 79 fish of 13 species. 164 (2.2%) as Hysterothylacium China type V from 20 fish of 4 species, 3 (0.04%) as Raphidascaris from 3 fish of 2 species and one was Pseudoterranova decipiens larva.

Anisakiasis of the gastrointestinal tract is caused by the ingestion of raw fish or uncooked food infested with Anisakis larvae. A large number of cases of gastric anisakiasis have been reported in countries where the eating of raw fish is customary. However, there have been few reports of anisakiasis of the colon confirmed by colonoscopy and also very few reports of endoscopic ultrasonographic findings of anisakiasis. A 47-year-old man had epigastric pain with nausea after eating raw anchovies. Endoscopy found a living tubular structure penetrating into the lesser curvature of the stomach and the midtranseverse colon area. It was withdrawn with biopsy forceps. We report a case of anisakiasis simultaneously invading the stomach and the colon confirmed by endosopic utrasonographic findings and biopsy findings.

Anisakiasis occurs when humans ingest raw or inadequately cooked saltwater fish or squid that is infested with anisakis larvae. The larvae invade the gastrointestinal mucosa and cause abdominal pain, nausea, vomiting and various gastrointestinal lesions. Anisakiasis of the stomach has been reported occasionally but involvement of the small bowel or colon is extremely rare. We report three cases of anisakiasis in the colon with a brief review of the relevant literature.

Gastric anisakiasis is a parasitic disease caused by the gastric mucosal penetration of the Anisakis larvae ingested with raw fish. Acute gastric anisakiasis is diagnosed by the endoscopic visualization of Anisakis larvae along with mucosal edema, erythema, hemorrhage, and/or an ulcer, whereas chronic anisakiasis is often observed as a localized tumor commonly occurring in the submucosal layer, and is characterized by eosinophilic granuloma with edema and embedded Anisakis larvae on pathological examination of surgical specimens. We report here a case of chronic gastric anisakiasis provoking a bleeding gastric ulcer, which is a rare clinical manifestation of this condition.

Anisakiasis occurs after ingestion of raw marine fish or inadequately cooked saltwater fish or squid containing nematode larvae of the Anisakis genus. Ingested larvae invade the gastrointestinal wall and cause clinical symptoms, including cramping, abdominal pain, nausea, vomiting, and various gastrointestinal lesions. Although enteric Anisakiasis is extremely rare, it can induce intestinal obstruction. Here, we report a case of intestinal obstruction caused by Anisakiasis, along with a brief review of the relevant literature.

Anisakidosis is caused by Anisakis simplex and other anisakids larvae parasitizing marine fish and cephalopods. A lot of case reports about anisakidosis have been published in Korea because of raw fish eating habits. Recently seafood consumption has continued to increase due to health concerns and thus, it increases the risk for infectious diseases including anisakidosis. The aim of this review is to analyze the clinical and epidemiological characteristics of anisakidosis during the last 10 years in Korea, based on the case reports published from 2000 to 2010. The incidence age was changed from 30s and 40s to 50s. The young generation was considered to consume seafood in various ways, including raw fish as well. The most noticeable change was the appearance of Anisakis allergy patients over the last decade. The patients showed abdominal pain, urticaria after eating sea food. It reaffirmed that anisakid infection induces not only gastric and intestinal anisakidosis but also cause allergic reaction. Anisakid should be considered as a possible causative food allergen provoking allergic responses after eating raw fish.
