Appendiceal Adenocarcinoma Presenting As Perforated Appendicitis

Abstract

Primary tumors of the appendix, specifically appendicular adenocarcinoma, are a rare malignant neoplasm of the gastrointestinal tract. We present a case of a 64-year-old female who had significant peritoneal adhesions from a previously perforated appendix involving the right ureter, bladder, and anterior abdominal wall after a course of perforated appendicitis, which was managed conservatively with drain placement with interval appendectomy. We are discussing this case in hopes of bringing awareness to the possibility of underlying malignancy in the setting of perforated appendicitis in patients of advanced age.

Appendiceal Signet Ring Cell Carcinoma: An Atypical Cause of Acute Appendicitis—A Case Study and Review of Current Knowledge

“…An accurate preoperative diagnosis of appendiceal neoplasms is crucial for planning appropriate surgical management in patients presenting with symptoms of acute appendicitis [20]. However, the lack of specific imaging findings can make it challenging to differentiate neoplastic lesions from other causes of acute appendicitis.…”

“…Out of these cases, 48.7% were positive mucinous adenocarcinomas while 51.3% were non-mucinous colon adenocarcinomas. (2) Other studies reveal that 0.9% to 1.4% of all appendectomies performed to treat acute appendicitis are of neoplastic origin Doi: 10.18004/sopaci.2023.abril.36 and that 2% and 6% of the patients diagnosed with acute appendicitis show the presence of an appendiceal mass often described as an inflammatory phlegmon or abscess. (3) Imaging reports play an important role in diagnosis.…”
