According to WHO, neuroendocrine tumors of the appendix (appendiceal carcinoids) are defined as 1. well-differentiated endocrine tumors with benign or uncertain behavior, 2. well-differentiated endocrine carcinoma and 3. goblet cell carcinoma. These tumors are usually diagnosed incidentally during appendectomy. Carcinoid syndrome is rare in appendiceal carcinoid. Tumor size greater than 2 cm is the most important parameter for prognosis. Most patients are cured by appendectomy (appendiceal tumors < or = 2 cm), tumors with a diameter > 2 cm should be managed by right hemicolectomy.
