homovanillic acid has been researched along with Craniopharyngioma in 3 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.
Craniopharyngioma: A benign pituitary-region neoplasm that originates from Rathke's pouch. The two major histologic and clinical subtypes are adamantinous (or classical) craniopharyngioma and papillary craniopharyngioma. The adamantinous form presents in children and adolescents as an expanding cystic lesion in the pituitary region. The cystic cavity is filled with a black viscous substance and histologically the tumor is composed of adamantinomatous epithelium and areas of calcification and necrosis. Papillary craniopharyngiomas occur in adults, and histologically feature a squamous epithelium with papillations. (From Joynt, Clinical Neurology, 1998, Ch14, p50)
