Abstract
ABSTRACT
Appendiceal carcinoids are the most frequent tumors arising from the appendix,
comprising between 32 and 57% of all the appendiceal tumors. The gross
appearance of the appendix showed perforation at the tip with 30 ml of
periappendicular collection. On histopathological examination, carcinoid tumor on
the tip of appendix was found with tumor cells arranged in tubules, acini and nests
infiltrating the muscularis propria and sub serosa. Perineural and vascular invasion
was not seen. Immunohistochemistry for Synaptophysin was positive with Ki-67
labelling index of 2%. We present a case of appendiceal neuroendocrine tumor
with the chief complaint of acute appendicitis.
