Mixed Adenocarcinoid Tumor Presenting as Acute Appendicitis

Abstract

Mixed adenocarcinoid tumors are not uncommon neoplasms of appendix. The clinical presentation of these tumors is often similar to that of acute appendicitis or may present as asymptomatic. These tumors are found incidentally during histopathological examination of the resected appendix following appendectomy or other abdominal procedures. Mixed adenocarcinoids usually behave as adenocarcinomas with rapid metastasis, so prognosis depends upon how aggressive the tumor behaves. The present study reports a case of a 53-year-old male who presented with abdominal pain and fever for 1 day and underwent successful appendectomy and recovered later. Subsequently, a mixed adenocarcinoma with carcinoid features of the appendix was diagnosed by histopathological examination. Follow-up examination of the patient in 3 months revealed metastasis of carcinoma to the peritoneum with adenocarcinoma features.
