“…The most common parasitic agent in the appendix has been reported as EV, while Tenia was the second most common in several studies, as in our series ( 15 , 19 , 22 , 26 , 37 ). Other parasitic agents such as Entamoeba histolytica , Balantidium coli , Entamoeba histolytica , Schistosoma , and Ascaris lumbricoides have been indicated in a few studies ( 2 ), though none of these were observed in the current study.…”

Objective: Parasites and plant seeds may both be found in appendectomy specimens. Each plant seed has a different appearance and can thus exhibit wide variations under the microscope. Fragmented seeds may histologically mimic parasites. The differential diagnosis between seeds and parasites can be challenging in such cases. This study aimed to determine the incidence of parasites, seeds, and foreign bodies in appendectomy materials and highlight the most characteristic histopathological features associated with these structures. Material and Method:In this study, pathology slides of 9,480 patients, who underwent appendectomy between 2010 and 2021, were reviewed, and cases that contained parasites, seeds, or foreign bodies were identified. We reviewed the literature on seeds and parasites in appendectomy specimens. Results:Parasites were observed in 56 (0.6%) cases. Of these cases, 45 had Enterobius vermicularis (80%), and 11 had Taenia subspecies (20%). Plant seeds were observed in 47 cases (0.5%), and were macroscopically recognizable in 5 of them as olive, lemon, and cherry seeds. Parasites and seeds were usually observed in the lumen of appendix vermiformis, filled with abundant fecal materials. Conclusion:Seeds are seen in approximately 0.5% of the appendectomy specimens. Though rarely seen, the fragmented seed appearance may cause diagnostic difficulties. In this context, the key morphological features of parasites and plant seeds outlined in this study may be helpful in their differential diagnosis.

Background: Parasitic infections are a major public health problem worldwide with one-quarter ofthe world’s population is suffering from it. Intestinal and extraintestinal parasitic infestations arerising in developing countries. There is a raise in the immunocompromised state in which tissueparasitic infestations are increasing which necessitates this type of study. Method: A retrospectivedescriptive study with data collected from histopathology register from January 2018 to December2020, all cases diagnosed as parasitic infestation with age, gender, location and histopathologicalevaluation with tissue response was analysed. Results: In the present study over 3 years 11parasitic infestations were identified. About 3(27.3%) cases of hydatid cyst, 5(45.5%) cases ofEnterobius vermicularis, 2 (18.2%) cases of cysticercosis and 1(9%) case of hard tick was identified.The most common age group affected was <25 years of age (54.5%). The most common parasitefound is Enterobius vermicularis in our study. Conclusion: A careful histopathological examinationto identify parasitic infestations in tissue sections will help to decrease morbidity and mortality byproviding specific treatment to the patient.

“…Parasitic infections are a recognized, though infrequent, cause of appendicitis, accounting for less than 1% of all cases in previous studies in other developing countries (2). The pathophysiology behind appendicitis suggests that obstruction of the appendiceal lumen by protozoans or cysts is rare, due to the Abdominal radiography after admission to the higher complexity institution showing coprostasis and distension of the small bowel without evidence of air-fluid levels.…”

“…Despite its widespread occurrence, the precise causes and risk factors for acute appendicitis remain the subject of ongoing research. Parasitic infections, though rare, are identified as a causative agent in close to 1% of cases ( 2 ). Prominent among the associated parasites are Ascaris lumbricoides, Trichuris trichiura, Enterobius vermicularis, Entamoeba histolytica, Giardia duodenalis, and various tapeworms ( 3 ).…”

IntroductionAcute appendicitis secondary to parasitic infections is uncommon, being detected in less than 1% of cases. Balantidium coli is a parasite found in pigs and primates with zoonotic potential. To date, only three cases of acute appendicitis induced by this parasite have been documented globally.CaseA 7-year-old female patient, who consumed pork daily, presented to the emergency department with a one-day history of abdominal pain in the lower quadrants, described as colic-like, alongside abdominal distension. Initial abdominal radiography led to a diagnosis of intestinal obstruction. Conservative management without therapeutic response necessitated referral to a higher complexity center. Upon admission, an abdominal computed tomography scan diagnosed acute appendicitis and secondary ileus. During surgical intervention, an appendiceal phlegmon formed by loops of the small intestine was mechanically released, revealing a perforated appendix with extensive fecal peritoneal contamination. Pathological analysis identified an inflammatory infiltrate and the presence of Balantidium coli trophozoites. Medical treatment included Piperacillin-Tazobactam and Metronidazole. The patient was discharged after 10 days of medical treatment.DiscussionAcute appendicitis caused by Balantidium coli is a rare occurrence. It is crucial to identify parasites in pathological samples due to their impact on postoperative management. The close contact between humans and pigs, especially in developing countries, suggests that the prevalence of parasitic infection and colonization by Balantidium coli may be higher than currently recognized. Regarding the identification of this patient's specific exposure, the regular consumption of pork suggests the hypothesis that improper processing is linked to the acquisition of the parasitic infection.
