Incidentaloma de ap?ndice cecal: casu?stica de um hospital geral

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.RESUMO - Racional: Os canceres de ap?ndice s?o raros e a maioria deles ? encontrada incidentalmente durante as apendicectomias por apendicite aguda. Objetivo: Avaliar a preval?ncia de casos de neoplasia de ap?ndice correlacionando com o perfil do paciente, tipos histol?gicos e suas frequ?ncias. M?todos: Realizouse a coleta de dados em um servi?o de patologia e um hospital geral, com o objetivo de identificar os pacientes diagnosticados com tumores malignos de ap?ndice cecal pelo estudo anatomopatol?gico de pe?as retiradas por apendicite aguda. Resultados: A preval?ncia de neoplasia epitelial prim?ria maligna de ap?ndice cecal foi de 1,08%. Na amostra estudada, 50% dos casos eram tumores neuroend?crinos, 35% neoplasias mucinosas e 15% adenocarcinomas. N?o houve diagn?stico de tumor misto adenoneuroend?crino na amostra analisada. A idade m?dia no momento do diagn?stico foi de 41,3 anos ? 20,4 (16-81), raz?o feminino/masculino de 3/1. Conclus?o: As neoplasias de ap?ndice cecal s?o raras e devem ser suspeitadas quando trata-se de uma mulher com mais de 40 anos, com sintomas de apendicite aguda. O tamanho, localiza??o, extens?o, margens e a presen?a de mucina s?o informa??es essenciais para o tratamento destes paciente
