Preferred Label : carcinoid tumor;
RADLEX synonyms : carcinoid;
Definition : A usually small, slow-growing neoplasm composed of islands of rounded, oxyphilic,
or spindle-shaped cells of medium size, with moderately small vesicular nuclei, and
covered by intact mucosa with a yellow cut surface. The tumor can occur anywhere in
the gastrointestinal tract (and in the lungs and other sites); approximately 90% arise
in the appendix. It is now established that these tumors are of neuroendocrine origin
and derive from a primitive stem cell. (From Stedman, 25th ed & Holland et al., Cancer
