Acute Appendicitis as First Sign of Colon Cancer in Young Patients

Acute appendicitis occurs with obliteration of the appendix lumen due to fecaloma, lymphoid hyperplasia, parasite, foreign body, and tumor. In recent years, it has been reported that obstruction by colon tumors also creates signs of appendicitis, based upon which the appendicectomy operation is done. Knowing that it can be seen in patients over the age of 40 who underwent appendicectomy operation, the necessary investigations for diagnosis should be conducted during preoperative, perioperative and even postoperative period. We aimed to emphasize the relation between acute appendicitis and colon cancer among young patients by introducing two patients under 40 years who were diagnosed with appendicitis, and underwent appendicectomy operation; however, they were later diagnosed with colon cancer.
