Incidentaloma de apêndice cecal: casuística de um hospital geral

Abstract

ABSTRACT - Background: Appendix neoplasia are rare and most of them are found incidentally during appendectomies for acute appendicitis. Aim: To evaluate the prevalence of appendix neoplasia correlating with patient profile, histological types and their frequencies. Methods: Data collection was performed in a pathology department and a general hospital, with the objective of identifying patients diagnosed with malignant cecal appendix tumors by anatomopathological study of specimen removed by acute appendicitis. Results: The prevalence of malignant primary epithelial neoplasia of the appendix was 1.08%. 50% of the cases were neuroendocrine tumors, 35% were mucinous tumors and 15% were adenocarcinomas. There was no diagnosis of adenoneuroendocrine mixed tumor. The mean age at diagnosis was 41.3 years ± 20.4 (16-81), female/male ratio of 3/1. Conclusions: Appendiceal neoplasms are rare and should be suspected when it is a woman over 40 years of age with symptoms of acute appendicitis. The size, location, extent, margins and presence of mucin are essential data for the treatment of these patients.
