Carcinoid tumors of the appendix in 25 children (21 girls, 4 boys) below 15 years corroborated the previously reported preponderance of females. 17 children were operated upon because of acute appendicitis, one because of oxyuriasis in the appendix and the remaining 7 because of diffuse recurrent abdominal pain. All the patients were subjected to appendectomy and one of them later also to right-sided hemicolectomy because of carcinoid in the margin of the resection of the appendix but not in the cecum. Despite deep infiltration of the wall of the appendix to the serosa in 9 children and lymph node metastases in one, no signs of a recurrence have been seen during follow-up of 5 to 17 years (mean 12 years).

In 895 patients operated on for acute appendicitis we found Yersinia enterocolitica in 41 cases. Another two cases were detected in postoperative serological examinations. Lymphadenitis mesenterialis was present in 17 cases during operation. Once we detected a regional enteritis. Histological examination of the appendix revealed a purulent inflammation in 21 cases and a phlegmonous-gangrenous inflammation in 4 cases. The other 18 patients suffered from Oxyuriasis, coprostasis or scars of the appendix. For this reason it is impossible to exclude an acute appendicitis in patients with cultural or serological identification of Yersinia enterocolitica.

The authors describe a case of appendicular oxyuriasis and then go on to review the international literature on this condition. Nothing in the case report provides the surgeon with useful pointers which may help him distinguish between appendicular oxyuriasis and common appendicitis. This is in line with all the existing literature which yields no elements capable of suggesting an accurate preoperative diagnosis. Only anamnestic evidence of previous oxyuriasis can help the clinician in this direction. It should be noted, however, that there are no significant differences in postoperative morbidity between "common" acute appendicitis and appendicitis due to oxyuriasis, when the parasitosis is adequately treated.

Retrospective analysis of the medical records of patients who underwent acute appendectomy in the Gastrointestinal Surgery Department of the Desgenettes Military Hospital in Lyon, France from the 1st of November 2009 to the 21th of February 2011, turned up two cases of appendicular parasitosis for a prevalence of 3.3%. Both patients presented acute appendicular oxyuriasis caused by Enterobius vermicularis that was discovered inadvertently after appendectomy. This unexpected diagnosis raises questions about the exact role of parasites in the physiopathology of appendicitis. Though appendicitis is the most common surgical emergency in France, appendix vermicularis is rare. In comparison, developing countries and particularly endemic areas such as sub-Saharan Africa show considerably higher appendicular parasitosis prevalence rates and greater variety in the parasites involved. The purpose of this article is to describe the different parasites with potential to affect the appendix, to discuss the different pathophysiological mechanisms underlying acute appendicitis, and to recall the need for medical treatment after appendectomy.
