Background: Appendiceal tumors correspond to 0.5% of all gastrointestinal tumors and their prognosis depends on the type of lesion. Aim: To analyze the clinical and pathological features of appendiceal tumors and their prognosis. Material and methods: Review of medical records of patients in whom an appendiceal tumor was detected during the pathological study in a Clinical Hospital, between 1981 and 2006. Results: Sixty seven patients were identified (mean age 45.3+ 19.6 years, 39 females). Fifty nine were operated due to the suspicion of an acute appendicitis, that was confirmed pathologically in 37. Thirty six patients had a neuroendocrine tumor, 18 had a benign tumor, seven an adenocarcinoma, five an adenocarcinoid and one a neuroendocrine plus a mucinous cystadenoma. A hemicolectomy was performed in a second operation in four patients with a carcinoid tumor, three with an adenocarcinoma, one with an adenocarcinoid and in one with a peritoneal pseudomyxoma. Five years survival was 100% in patients with benign tumors, 97% in those with neuroendocrine tumors, 75% in those with adenocarcinoid tumors and 62% in those with adenocarcinoma. Conclusions: Most appendiceal tumors were discovered during the pathological study of the surgical piece of appendicectomies performed due to the clinical suspicion of an acute appendicitis. Survival of patients was dependent on the type of tumor
