Summary
A 28-year review of the records at Hines V.A. Medical Center revealed 17 primary epithelial tumors of the appendix. Five of these tumors were benign and 12 malignant. It is suggested that the term mucocele be abandoned, because it represents the end result, rather than a definite pathologic entity. The majority of benign tumors and carcinoid tumors of the appendix are discovered incidentally to other procedures. The majority of adenocarcinomas cause symptoms and signs of appendicitis.
Simple appendectomy is sufficient treatment of all benign tumors of the appendix, and for all carcinoids that show no gross local metastases and are less than 2 cm in diameter.
Simple appendectomy followed by right hemicolectomy or initial right hemicolectomy is the treatment of choice for all carcinoids of the appendix that show gross local metastases and are 2 cm or more in diameter and for all adenocarcinomas of the appendix, whether mucinous or colonic, in the absence of distant metastasis.
A new classification for primary epithelial tumors of the appendix is suggested.
