title: Carcinoid tumours of the appendix.
abstract: Appendicular carcinoid tumours in 147 patients are presented. Two patients had evidence of metastatic spread at the time of presentation. Both patients had primary tumours less than 2 cm in diameter. Size remains the most reliable guide to the malignant potential of these tumours. If, after simple appendicectomy, a carcinoid tumour is found with a post-formalin fixation diameter greater than 1.5 cm then a subsequent right hemicolectomy should be considered.
