This is the first report in the literature of a non-seminomatous metastasis from an occult testicular primary that presented as an acute appendicitis. The report highlights the necessity of testicular re-imaging in cases of occult malignancy and reviews the association of chromosome 12 with embryonal germ cell tumours.

Granulomatous inflammation of the appendix is uncommon. It can be caused by a variety of conditions, including systemic disorders such as Crohn's disease and sarcoidosis, and infections such as mycobacterium tuberculosis, yersinia pseudotuberculosis, parasites and fungi. Granulomatous appendicitis as an isolated pathological entity unassociated with systemic disease is rare. Isolated granulomatous inflammation of the appendix of unknown aetiology, otherwise known as idiopathic granulomatous appendicitis is extremely rare. Patients with this condition present with the typical signs and symptoms of acute appendicitis. We present a series of patients with isolated granulomatous inflammation of the appendix, and discuss the difficulties encountered in the management of this condition.

Objective: To find out whether the removal of the appendix from patients in whom laparoscopy for acute right iliac fossa pain shows no abnormality is justified to avoid the risk of missing acute appendicitis., Patients: The records of patients who, between 1990 and 1997 had emergency laparoscopy for acute right iliac fossa pain were reviewed. Only those in whom laparoscopy had shown no abnormality and had not had the appendix removed were included in the study., Methods: Outcome was assessed by telephone questionnaire to the patient, the general practitioner, or both., Results: Emergency laparoscopy had been done for 254 patients. No abnormality was detected in 41. Full follow up was available on 34 patients (83%). 21 patients have remained entirely free of symptoms. Of the 13 patients who had recurrent symptoms, 2 subsequently had a histologically normal appendix removed, yet still had symptoms; 2 had a second laparoscopy that showed no abnormality; 5 had ultrasound; and 4 had colonoscopy or a barium enema examination., Conclusion: Removal of an appendix that looks 'normal' at emergency laparoscopy for right iliac fossa pain is unjustified.

The aetiology of acute appendicitis remains uncertain. H. pylori is viable outside the gastroduodenum, however its pathological role outside this area has not been fully investigated. Ten consecutive patients with a histological diagnosis of acute appendicitis were investigated for H. pylori status by serology, and by culture, histology, and polymerase chain reaction (PCR) analysis of the appendiceal specimens. One patient had positive serology for H. pylori, however PCR analysis was negative. Culture failed to reveal H. pylori colonies. Histology in 5 cases did reveal organisms with a morphological appearance of H. pylori, but PCR analysis confirmed that H. pylori was not present. Using a variety of methods, with PCR acting as the 'gold standard', we have shown that H. pylori is not associated with acute appendicitis.
