We report a case of acute abdomen due to appendicular lumen occlusion by anisakis larvae. This is the first case of human anisakiasis known in Spain, and the first case of acute appendicitis, in the medical World literature, produced by this nemathode. The association of myalgias and arthralgias stands out, being in this aspect the second case found the in medical litterature.

The eosinophilic granuloma of the gastrointestinal tract was in recent years observed more frequently in infections with larvae of the herring-roundworm Anisakis. The associated symptoms are similar to those of acute appendicitis. Proof of a worm within the granuloma is usually easy, where as the classification to individual species is difficult, since the larva mostly occurs as a largely decomposed corpus. Due to the long period between infection and detection of the eosinophilic granuloma patients often do not remember the origin of infection.

The authors recently encountered a patient with omental anisakiasis who presented with features of acute appendicitis and who made an uneventful recovery following resection of an inflammatory omental mass containing the larva(e). Anisakiasis refers to infestation of humans by species of marine nematode larvae belonging to the subfamily Anisakinae. Although this condition is rarely reported in the United States, it has been well described both in Holland and in the Orient. Several publications in the Japanese literature have detailed the morphology of the parasite and the clinical symptoms of infestation. The source of infestation is most often raw or uncooked fish, the latter widely enjoyed as a foodstuff in the Orient, but less popular in the United States. With the growing popularity of "sushi" bars and the increasing numbers of Americans developing a taste for raw fish, this condition may become more prevalent in the future.

A case of small-bowel obstruction occurred secondary to an uncommon parasitic disease, anisakiasis. Intestinal obstruction is a rare manifestation of this disease. Anisakiasis may be seen initially with nausea and vomiting or may mimic acute appendicitis or Crohn's disease. The predisposing factor in all cases is the ingestion of raw fish, and the disease is preventable by cooking fish at greater than 60 degrees C for a short time or by freezing at less than -20 degrees C for more than 24 hours. Anisakiasis should be considered in the differential diagnosis of small-bowel obstruction in patients whose diet includes raw fish.

A hazard associated with eating raw fish is presented. The larval nematode Anisakis marina ('herring worm') is a recognised public health problem in Japan, and cases have been reported in the UK. The intestinal burrowing of the larval form causes acute abdominal symptoms clinically resembling acute appendicitis. Operation is required; no antiparasitic agent is available.

A case of extra-gastrointestinal infection by Anisakis in a woman living in Catania (Sicily, Southern Italy) is described. The patient complained of severe pain in the ileocecal region, and a diagnosis of acute appendicitis led to an appendectomy. During the intervention, a laparoscopic exploration showed a nodule on the large omentum that was surgically removed. Parasitological diagnosis was achieved on the basis of morphological observations carried out on the histological sections of the nodule.

Anisakidosis is the infestation of man by the larval stage of the parasite Anisakis simplex. A history of ingestion of raw or undercooked fish up to 48-72 hours before the onset is highly orientative. Based on the location of the lesions, various types of human anisakidosis have been identified: gastric, intestinal and luminal forms constitute the majority of cases and symptoms often mimic a variety of acute conditions such as gastritis, acute appendicitis, diverticulitis, or ileitis. We present a case of a young woman admitted to our department with acute abdominal pain. A history of raw fish ingestion was recorded. The patient was submitted to explorative laparoscopy in which an oedematous, thickened segment of ileum was observed. Therefore a small laparotomy was performed, followed by resection of the thickened ileum. The histological examination revealed transmural inflammation with marked infiltration of eosinophils. High levels of total IgE and Anisakis simplex-specific IgE were recorded. Anisakidosis is an underestimated cause of acute abdomen, and should be taken into consideration as a differential diagnosis in these conditions. Nevertheless, in most cases, the correct approach could prove difficult, because surgery may be necessary in these settings, allowing the diagnosis only by histological and parasitological investigation of the resected specimen.
