 Appendiceal tumors are classified into six categories according to the General Rules for Clinical and Pathological Studies on Cancer of Colon,Rectum and Anus. Of these categories carcinoid tumor, mucinous cystadenoma, mucinous cystadenocarcinoma and adenocarcinoma are common while the other very rare.

 For the last 10 years, 14 cases of appendiceal tumor were experienced at Department of Surgery in Ogaki Municipal Hospital accounting for 0.3 percent of 4,654 cases of either appendectomy or right hemicolectomy. These 14 cases were pathologically classified into 5 mucinous cystadenomas, one mucinous cystadenocarcinoma, 2 carcinoid tumors, 5 adenocarcinomas and one malignant lymphoma. Based on these cases and review of literatures, mention was made regarding the diagnosis, treatment and prognosis of appendiceal tumors.

 Appendiceal tumors were visualized on ultrasound,CT and other modalities, but preoperative histologic diagnosis was difficult. The prognosis of benign tumor and small carcionoid tumor of the appendix were excellent, while that for malignant neoplasm poor. In our series a patient with mucinous cystadenocarcinoma,3 patients with adenocarcinoma and a patient with malignant lymphoma died of recurrence within two years after surgical treatment. Although appendectomy is enough for benign tumors and small carcinoid tumors and considered the treatment of choice, right hemi-colectomy with lymphnode dissection should be per-formed for large carcinoid tumors and malignant neo-plasms.
