Adenocarcinoma of the appendix: a clinicopathologic study.

Clinicopathologic correlation and survival were evaluated in 11 patients with adenocarcinomas of the appendix. This extremely rare tumor was seen most often in patients in the fifth decade of life. Acute appendicitis was the most common mode of presentation (8/11). A few patients (3/11) showed signs of distant metastases from an occult primary tumor in the appendix.
