homovanillic acid has been researched along with Carcinoid Tumor in 4 studies
Homovanillic Acid: A 3-O-methyl ETHER of (3,4-dihydroxyphenyl)acetic acid.
homovanillate : A hydroxy monocarboxylic acid anion which is obtained by deprotonation of the carboxy group of homovanillic acid.
homovanillic acid : A monocarboxylic acid that is the 3-O-methyl ether of (3,4-dihydroxyphenyl)acetic acid. It is a catecholamine metabolite.
Carcinoid Tumor: 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 Medicine, 3d ed, p1182)

( Knight, JA; Robertson, G; Wu, JT, 1983) |
| "Although both carcinoid tumors and pheochromocytomas arise from neural crest origin, they are thought to each secrete distinctive monoamines; carcinoid tumors, which contain tryptophan hydroxylase, secrete serotonin, and pheochromocytomas, which contain tyrosine hydroxylase, may secrete dopamine (DA), norepinephrine (NE), or epinephrine (E)." | 1.27 | Increased dopamine production in patients with carcinoid tumors.
