Neuroendocrine Tumour Mucinous Adenocarcinoma and Signet-Ring Cell Carcinoma of the Appendix: Three Cases and Review of Literature

摘要

Appendiceal neoplasms are relatively common tumours. Although these tumours are often associated with signs and symptoms of acute appendicitis, most appendiceal neoplasms are clinically silent. Appendiceal neoplasms are found in 0.7 to 1.4 per cent of all appendectomy specimens. The classification of these tumours is still confusing and precise treatment methods for these neoplasms remain unclear. First choice therapy of these neoplasms is still a surgical treatment and the type of operative procedure is determined by histology and metatstatic risk. Here, we report three cases of appendiceal neoplasms and make a short review of literature.
