FLORIAN, María Cristina; URIBE, Alejandro  e  CARDONA, Claudia Patricia. Carcinoid tumor of the appendix. Case presentation. rev. colomb. cir. [online]. 2011, vol.26, n.1, pp.62-66. ISSN 2011-7582.

The carcinoid tumors of the gastrointestinal tract originate in endocrine cells located in the crypts of the mucosa of the digestive tract, usually called Kulchitsky cells. The appendix is the most common site for the development of intestinal carcinoid tumors, which are usually located at the tip of the appendix; they also occur in the small bowel, especially the ileum, rectum, stomach and colon. The peak incidence is in the third and fourth decades of life. These tumors are found in about one of every 300 appendectomies, routine preoperative detection is rare, and they represent the most common tumor of the appendix. Almost always they are found as appendicitis. We report a case of appendiceal carcinoid tumor. The patient is a male aged 30, which underwent appendectomy because of appendicitis. The pathology study confirmed a well differentiated neuroendocrine tumor of 1.2 cm in diameter with involvement of the entire wall including the serosa and focally the mesoappendix, tumor vascular invasion, base of the appendix free of tumor, perforated appendicitis. Behavior will be discussed against the findings of this tumor.
