A Case of Acute Appendicitis Associated with Ileocecal Polypoid Lesion

Abstract

We experienced a case of acute appendicitis associated with ileocecal polypoid lesion. The patient was a 74-year-old female and she had had continuous lower abdominal pain for 10 days. After conservative therapy, she was performed colonoscopy. It showed small polypoid lesion at the appendicial orifice. Histopathological findings of biopsy specimen showed infiltration of inflammatory cells in submucosal space and nucleic atypia of some infiltraded lymphcytes and they suggested us that malignant lymphoma could not be denied.
According to these findings, she was undergone ileocecal resection to determine the characterisity of the tumor and so as not to recurrent of appendicitis. Histopathological findings of the resected specimen showed atypical ephithelium at the polypoid lesion without evidence of malignancy and it was considered as a regenerative change. After operation she did well.
In literature, there are some case reports about appencial diseases include malignancies, Crohn's disease and appendicitis, and few cases of them were diagnosed correctly preoperatively because of diagnostic difficulties. There is only a little information about appencial diseases like this case. Pancity of the information prompt us to present a case.
