Appendiceal Carcinoid tumor (2 of 3)

Carcinoid tumor of the appendix

Appendix — Carcinoid tumors are the most common
neoplasms in the appendix. Approximately 1 in 300
appendixes contain a carcinoid tumor, almost always as a
incidental finding. Appendiceal carcinoids are felt to arise
from endocrine cells in the lamina propria and submucosa

Metastatic Carcinoid tumors and the Carcinoid
Syndrome — As noted previously, 90
percent of patients with the carcinoid syndrome have
metastatic disease, typically to the liver. Exceptions are
bronchial and ovarian tumors that can produce symptoms
without metastasis. Patients with the carcinoid syndrome
may benefit from therapies for the different components of
the syndrome.
