Enterobius Vermicularis Related Acute Appendicitis: A Case Report and Review of the Literature
While the debate on the association between Enterobius vermicularis (E. vermicularis) and acute appendicitis has not been settled, a few case reports of this very rare encounter are beginning to come to light. While E. vermicularis is one of the most common parasitic infestations around the world, acute appendicitis, on the other hand, is also a commonly encountered condition in general surgery. However, the association between the two remains controversial. Here we present a case report of a young woman with appendicitis associated with (E. vermicularis).
Acute Appendicitis Caused by Enterobius Vermicularis: Case Report
Bezmialem Science, 2021
Enterobius vermicularis is one of the most common bowel parasites worldwide. It can be located in the lumen of the ceacum and appendix and rarely causes acute appendicitis disease. In this case, we present a 36 years old female patient who underwent appendectomy with the preliminary diagnosis of acute appendicitis. Enterobius vermicularis was detected by histopathological examination.
Enterobius vermicularis: A Controversial Cause of Appendicitis
DOAJ (DOAJ: Directory of Open Access Journals), 2004
Enterobiasis is undoubtedly one of the most common human helminths infections through the world, with an estimate of 1000 million cases worldwide. Although adult worms and their eggs are frequently found in inflamed appendices, but the role of the parasite in producing appendicitis in humans still remains controversial. Although acute appendicitis may occur at any age, but it is relatively rare at the extremes of age. A histopathological study of infested appendices with Enterobius vermicularis was performed in Khuzestan province, south western Iran, during 2001 to 2003. All 40 samples had surgically been removed during the emergency operations and histopathological process with (H&E) staining has been performed for each. One of the main objects of this work was to collect more data about the possible role of this highly prevalent human round worm as a causative agent of appendicitis in humans, leading to different types of appendicitis in this part of the country. In this occasion over the slide examinations of the tissue sections, fewer cases than expected, with worm infested appendices were seen exclusively affected with this parasite.
Enterobius vermicularis: A rare Cause of Appendicitis
Turkish Journal of Parasitology, 2012
Objective: Although appendicitis is one of the most common causes of emergency surgery, parasites are rarely found associated with infl ammation of the appendix. The aim of this study is to establish the prevalence of Enterobius vermicularis in surgically removed appendices, as well as to determine its possible role in the pathogenesis of appendicitis. Methods: A retrospective analysis of all the appendices removed during the last 20 years at a tertiary university hospital. Appendices removed during the course of another intra-abdominal procedure were excluded from the study. Results: All 1085 surgical specimens removed from patients with clinical appendicitis were evaluated. Enterobius vermicularis was found in seven appendices (0.65%) with clinical symptoms of appendicitis. The parasite was most frequently identifi ed in appendices without pathological changes (6/117). There was no case of chronic appendicitis presenting E. vermicularis infestation, while the parasite was rarely related to histological changes of acute appendicitis (1/901).
Acute Appendicitis Secondary to Enterobius Vermicularis Infestation: A Case Report
European Journal of Medical and Health Sciences, 2020
The association of Enterobius vermicularis and appendicitis were recognized in the late XIXe century, when an incidence of 19% of appendicular infestation in children with appendicitis was reported. Other studies showed that the relationship between this parasitosis and appendicitis varied from 0.2 to 41.8 worldwid. In this paper we present an adult patient with acute appendicitis caused by Enterobius Vermicularis discovered in per-surgical procedure, and we’re going to discuss on the bases of the literature the epidemiological, clinical, and therapeutic characteristics of the appendicular localization of oxyurosis.

Background: Appendiceal parasites can cause symptoms of appendicitis. Although the symptomatology imitates acute appendicitis clinically, the true nature of disease is diagnosed through histological examination. The aim of this study is to therefore determine the prevalence of E. Vermicularis in appendicectomy specimens to relate this to acute inflammation histologically.Materials & Methods: Histological data on all appendectomy specimens with a clinical diagnosis of acute appendicitis were retrieved from the archives of department of pathology, B.P.K.I.H.S, over the period of five years (January 2004- December 2008) and was analyzed retrospectively.Results: There were a total of 1528 patients. M:F ratio being 1.2:1.Inflamed appendix constituted for 94.24% of all cases. There were a total of six (0.39%) appendicectomy specimens which showed presence of oxyuriasis appendix. Though all patients with oxyuriasis presented with appendicial colic only one (1) out of the six cases of oxy...

Enterobius vermicularis is one of the most common intestinal parasite in human. The main objective of this study is to determine the role of E. vermicularis in appendicitis through histopathological examination. A cross sectional study included 200 patients who had appendectomy from three hospitals in Gaza strip. The inflamed appendix was the cause of attending the hospital. Histopathological examination for each appendix was carried out. A questionnaire was designed (interview with patients who underwent appendectomy), and information were obtained from patient and analyzed by using SPSS. The study showed that 30 (15.0 %) of 200 appendices had E. vermicularis in histopathological examination. It was found that ages of patients with histologically proven E. vermicularis in appendices less than 18 years old was found to be (18.2 %). Regarding sex, (16.5 %) of females, (14.0 %) of males patients had E. vermicularis in appendices. Patients who had the highest infection with E. vermicularis were students (17.3 %). In conclusion E. vermicularis occurs more frequently inflamed appendices than in normal. From these results we can conclude that E. vermicularis could be associated to cause of appendicitis in Gaza strip.

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.

This study aimed to assess the relationship between Enterobius vermicularis and appendicitis by determining the frequency of E. vermicularis in appendectomy specimens obtained after a preliminary diagnosis of appendicitis. Materials and Methods: Retrospective evaluation was conducted on the results of appendectomy specimens examined histopathologically at Van Training and Research Hospital Pathology Laboratory from March 2016 to March 2022. Hematoxylin-eosin stained slides from 7,814 appendectomy specimens were scrutinized for the presence of E. vermicularis, acute inflammation, fecaloid material, lymphoid hyperplasia, obliteration, perforation, phlegmonous appendicitis, and peritonitis. Furthermore, slides stained with hematoxylin-eosin (H&E) from patients testing positive for E. vermicularis were re-evaluated by the author in pathology. Results: E. vermicularis was identified in the appendectomy specimens of 50 (0.64%) out of 7,814 patients who underwent appendectomies. In histopathological examinations, the occurrence of lymphoid hyperplasia and fibrous obliteration was higher in E. vermicularis-positive patients compared to those who teste negative. Findings revealed that the mean white blood cell count (WBC) was lower in E. vermicularis-positive patients than in negative patients, while the mean eosinophil percentage (EO%) was higher. Conclusion: These findings imply that although the parasite is not a direct causative factor for appendicitis, it may contribute to the development of factors that result in obstruction in certain cases.
