follicular adenoma


fol·lic·u·lar ad·e·no·ma

an adenoma of the thyroid with a simple glandular pattern.

adenoma

(ad?e-no'ma) ('ma-ta) plural.adenomasplural.adenomata [ aden- + -oma] A benign tumor made of epithelial cells, usually arranged like a gland. adenomatous (-no'ma-tus), adjective

Patient care

Initial care focuses on identifying the sites of tumors, performing biopsies or noninvasive studies to determine if they are benign or malignant, and discussing findings with the patient, the patient's family, and significant others. Disease-specific education is provided to explain diagnostic options and support the patient. Malignant adenomata may need surgical removal; they may be treated with a combination of therapies, including surgical removal, radiation therapy, hormone therapy or chemotherapy. Patient education, esp. with respect to the side effects of therapies and implementing strategies to ameliorate the side effects, is crucial. General emotional support of the patient eases anxiety, isolation, and suffering.

acidophilic adenoma

An adenoma of the pituitary gland in which cells stain with acid dyes. Such staining was formerly used to suggest the presence of growth hormones, the cause of acromegaly and gigantism. Immunocytochemistry is the modern means of classifying pituitary tumors. Synonym: eosinophil adenoma; somatotroph adenoma

adrenocorticotrophin-secreting adenoma

A pituitary adenoma that secretes adrenocorticotropic hormone, the releasing hormone responsible for Cushing's syndrome.

basophil adenoma

, basophilic a.An adenoma of the pituitary gland in which cells stain with basic dyes. The term was formerly used to suggest tumors that secreted adrenocorticotrophin (ACTH), the cause of Cushing syndrome. Those tumors are now identified more directly by the identification (by immunocytochemistry) of ACTH in tumor cells. The use of hematoxylin and eosin staining to identify pituitary tumors is obsolete.

chromophobe adenoma

An adenoma of the pituitary gland composed of cells that do not stain readily. The term has more historical value than descriptive value and is no longer in use.

cystic adenoma

Cystadenoma.

eosinophil adenoma

, eosinophilic a.Acidophil adenoma.

fibroid adenoma

Fibroadenoma.

follicular adenoma

An adenoma of the thyroid.

gonadotroph-cell adenoma

The most common macroadenoma of the pituitary gland. It secretes either luteinizing hormone or follicle-stimulating hormone.

Hürthle cell adenoma

See: Hürthle, Karl W.

lactotroph adenoma

Prolactinoma.

malignant adenoma

Adenocarcinoma.

papillary adenoma

An adenoma with nipple-shaped glands.

pituitary adenoma

An adenoma of the pituitary gland, often of one of its functional cell types. It may produce excessive amounts of hormones such as prolactin, growth hormone, or adrenocorticotrophic hormone, or it may be clinically silent.

prolactin-secreting adenoma

Prolactinoma..

sebaceous adenoma

Enlarged sebaceous glands, esp. of the face. Synonym: adenoma sebaceum

adenoma sebaceum

Sebaceous adenoma.

somatotroph adenoma

A growth-hormone-secreting tumor of the anterior pituitary that causes acromegaly or giantism.

villous adenoma

A large polyp of the mucosal surface of the large intestine. It has the potential to develop into cancer.
