Appendiceal tumours are rare and often discovered unexpectedly in an acute situation in which decision-making is difficult. We report the spectrum of appendiuar tumours seen in our institution over a period of more than 10 years, and discuss the clinicopathological behaviour, investigations, surgical procedures and outcomes in these patients. We have also reviewed the literature with regard to appendiceal tumours. Appendicular tumours were identified from the database of 1646 appendictomies (18% in children) performed in single centre and case notes were reviewed. Clinical presentation, investigations, histopathology, surgical procedures and outcome were analysed. Twelve patients with appendiceal tumours were identified (0.72%): 8 carcinoid, 2 mucinous (mucocele) and 2 adenocarcinoma. All the patients with a carcinoid tumour presented with features suggestive of acute appendicitis and were diagnosed postoperatively following appendicectomy and formal histology. No further surgical intervention was required as these lesions were less than 1cm away from the base of the appendix. One of the patient with mucinous cystadenoma presented acutely and underwent an appendicectomy; in the other patient with chronic pain, apreoperative MRI suggested the diagnosis leading to a planned hemicolectomy as the lesion was close to the base of the appendix. While one of the patient with an adenocarcinoma localized to the appendix did well following a right hemicolectomy, the other patient with disseminated disease succumbed within a year. Carcinoid tumours are the commonest appendiceal tumours, which present often as acute appendicitis. While appendicectomy would be adequate in most of these patients, in patients with a cystadenoma close to the base of the appendix or in case of a carcinoma, a right hemicolectomy is the appropriate option. While the prognosis is good in patients with carcinoid tumour and cystadenoma, it remains dismal in patients with disseminated malignant disease.
