ABSTRACT: Introduction
and Aims: Acute appendicitis is a commonly established
diagnosis in the approach of abdominal pain. It is usually due to an acute
inflammatory process in the appendix. Nevertheless, there is a small percentage
of cases due to non-frequent etiologies that are only identifiable based on histopathological
analysis. The aim of this study was to determine the prevalence and
characterization of these unusual findings. Materials and Methods: The
present study was a cross-sectional study in a third-level hospital in Mexico
City. Clinical information was collected from unusual findings in the histopathological
analysis of 1018 appendectomy specimens between January 2012 and April 2017. Results: In total, 1018 appendectomy specimens were included. In 11 of those
appendices (1.08%), unusual findings compatible with appendicular tumors were
identified. Carcinoid tumor found in the tip of the appendix was the most
frequently reported finding. The muscular layer was affected in most cases; up
to 25% of regional ganglia were invaded. Most of the patients presented with
abdominal pain and clinical signs suggestive of acute appendicitis. The
preferred approach for surgical treatment was laparoscopic. Discussion and
Conclusion: The prevalence of unusual findings in our population was 1.08%,
with carcinoid tumors the most frequently established diagnosis among those
(0.58%), according to previously reported literature data.
