The authors present a case of enterobiasis of the appendix. Enterobius infection is an uncommon cause of acute appendicitis. Preoperative diagnosis of pinworm infestation is almost impossible unless there is a strong clinical suspicion. Parasites may produce symptoms which resemble acute appendicitis. Careful observation of the appendix stump may lead to intraoperative diagnosis of enterobiasis. A quick diagnosis and appropriate treatment may prevent future complications.

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.

Gastrointestinal infection due to Enterobius vermicularis occurs worldwide and is considered to be the most common helminth infection. The simple presence of E. vermicularis in the appendix usually produces symptoms of acute appendicitis. The association of this parasitic infestation with acute appendicitis varies from 0.2%-41.8% worldwide. We present a case of a 15 year old female with enterobiasis of appendix presented with clinical features of acute appendicitis. The appendix was surgically removed and the specimen was pathologically diagnosed to contain of E. vermicularis in non-inflamed and histologically normal appendix. Even if this condition is not uncommon in the Greek population, to the best of our knowledge this is the first report presented in the English literature.

A 29 year old female HIV-positive patient presented in emergency with acute right lower quadrant abdominal pain, fever, tenderness and positive Blumberg sign. Laboratorial tests revealed eosinophilia, anaemia and leukocytosis. She underwent exploratory laparotomy followed by appendectomy. The pathological analysis of the appendix revealed acute appendicitis, accentuated eosinophilia and infestation by Strongyloides stercoralis and Enterobius vermicularis. She did well after surgery and adequate treatment. To the authors' knowledge, this is the first case of eosinophilic acute appendicitis caused by these two parasitic worms reported in the medical literature.

A 17-year-old female patient presented with the clinical features of an acute appendicitis. During laparoscopic exploration a macroscopically normal appendix was found. Since there were no intra-abdominal abnormalities found, the appendix was resected. Anatomopathology demonstrated Enterobius vermicularis, a pinworm infecting only humans, and mostly living in the caecum. This parasite is responsible for possibly the most common helminthic infection in the developed world. Its role in the pathogenesis of acute appendicitis is controversial, but more recent studies indicate a stronger association between enterobiasis and appendicitis. Often, enterobius mimics appendicitis by obstructing the lumen of the appendix, thereby causing appendiceal colic. This case report stresses the importance of microscopic examination of all appendectomy resection specimens. In case of enterobius infestation, systemic therapy of patient and family is necessary.

Acute appendicitis is the most common surgical emergency worldwide. However, it can still present a challenging diagnosis especially in the young, elderly and those individuals of reproductive age, thus encompassing a wide spectrum of varied clinical presentations. Parasitic infections of the appendix are a rare cause of acute appendicitis. However, they must be considered in children presenting with abdominal pain. We report a case of Enterobius vermicularis infestation mimicking the features of acute appendicitis in a 10-year-old girl. This case is a cautionary reminder of the importance of considering E. vermicularis infestation in children presenting with abdominal pain, but who do not have a significantly raised white cell count or high Alvarado scores. A history of anal pruritus is the most characteristic symptom, but the parasites can cause severe abdominal pain mimicking appendicitis. Prompt recognition and a high clinical index of suspicion are required to prevent an unnecessary appendicectomy. Caution is advised when performing a laparoscopic appendectomy, as in our case, to prevent contamination of the peritoneum. This infestation is easily treatable with mebendazole.

Enterobius vermicularis (EV) is a pinworm which commonly resides in the lumen of the intestinal tract and lays eggs on the perianal skin. However, rarely the worm can infest various other sites in the body and cases with infestation of such ectopic sites have been reported in literature. Rare cases of mesenteric lymph node involvement have also been reported. We report a case in a young male who presented with signs and symptoms of acute appendicitis. During surgery, enlarged mesenteric lymph nodes were identified. Histological examination revealed adult worm in the appendiceal lumen. Histological examination of mesenteric lymph node revealed degenerated worm surrounded by caseating chronic granulomatous inflammation. We conclude that EV infestation should be considered in the differential diagnosis of enlarged mesenteric lymph node with chronic granulomatous inflammation, especially in young patients and when accompanying bowel tissue also reveal the helminth.

Enterobius vermicularis is the most commonly identified parasite incidentally found within the appendix of a clinically diagnosed appendicitis. This parasitic cause of appendicular colic, primarily affecting children, is an important cause of negative appendicectomy. We report an unusual and interesting case of a young female who presented with clinical features of acute appendicitis. Laparoscopic appendicectomy revealed the presence of an Enterobius vermicularis infestation originating from the lumen of her vermiform appendix. Our case report is supplemented with a review of the literature, an overview of the parasitology, and discussion of pertinent symptomatology and peri-operative management strategies.
