TWO RESECTED CASES OF APPENDICEAL CANCER IN YOUNG PATIENTS

Abstract

Appendiceal cancer is extremly rare and common in aged patients. We experienced two young patients with appendiceal cancer which were detected with manifestations mimicking acute appendicitis.
Case 1: A 21-year-old man underwent a laparotomy with a preoperative diagnosis of local peritonitis due to chronic appendicitis. During operation, pseudomyxoma peritonaei arising in the appendix was found. The appendix and metastatic greater omentum were removed as possible as we could. Microscopic examination of the resected appendix showed pseudomyxoma peritonaei caused by a mucinous cystadenocarcinoma.
Case 2: A 33-year-old woman underwent a laparotomy with a preoperative diagnosis of acute appendicitis. During operation, the swollen appendix to 20cm in size was noted. Appendectomy was performed. Microscopic examination of the resected appendix revealed well diffentiated adenocarcinoma. So, an ileocecal resection with lymph node dissection was added.
We should keep this rare tumor in mind as a probable differential diagnosis for appendicitis, and carefully examine the resected material of the appendix pathologically, regardless of age.
