Abstract
Neuroendocrine neoplasms are the most common epithelial tumors among appendix tumors. Appendix tumors that are completely or partially composed of neuroendocrine cells are divided into two categories: Classic carcinoid tumors and goblet cell carcinoid tumors (GCCT). They are known to progress more aggressively than classic (neuro) endocrine tumors. In this study, three cases with acute appendicitis symptoms are presented, including their clinical and histopathological findings. Microscopic examination detected GCCT in two cases and mixed adenoneuroendocrine carcinoma in one case, in addition to acute appendicitis.
Core tip: Goblet cell carcinoid is a much more aggressive tumor than classic carcinoid, particularly if the tumor shows transmural involvement or if it has extended to the cecum at the time of the operation. This paper presents three cases clinical and histopathological features. Two were diagnosed as goblet cell carcinoid tumor and one was diagnosed as mixed adenoneuroendocrine carcinoma.
