| lymphoma, large-cell, follicular | Malignant lymphoma in which the majority of neoplastic cells within the follicles are large cleaved or noncleaved cells. The degree to which the follicular centre cells retain their ability to form follicles varies with the state of B-cell transformation. (12 Dec 1998) |
|---|---|
| lymphoma, mixed-cell, follicular | A low-grade malignant lymphoma of follicular pattern in which there is no clear preponderance of one cell type (small or large) over another. The large cells, cleaved or noncleaved, are often 2-3 times larger in diameter than normal lymphocytes. (12 Dec 1998) |
| lymphoma, small cleaved-cell, follicular | A low-grade malignant lymphoma of predominantly follicular pattern. Follicles are of relatively uniform size and shape and the cells are usually somewhat larger than normal lymphocytes. Nuclei are irregular with prominent indentations and cytoplasm can rarely be identified. Cells exhibiting these characteristics are often called centrocytes. (12 Dec 1998) |
| accessory thyroid | An isolated mass, or one of several such masses, of thyroid tissue, sometimes present in the side of the neck, or just above the hyoid bone (suprahyoid accessory thyroid gland), or even as low as the arch of the aorta. Synonym: glandula thyroidea accessoria, accessory thyroid, prehyoid gland, suprahyoid gland, thyroidea accessoria, thyroidea ima, Wolfler's gland. (05 Mar 2000) |

| cancer, thyroid | Cancer of the gland in front of the neck that normally produces thyroid hormone which is important to the normal regulation of the metabolism of the body. There are four major types of cancer of the thyroid gland. Persons who received radiation to the head or neck in childhood should be examined by a doctor every 1 to 2 years. The most common symptom of thyroid cancer is a lump, or nodule, that can be felt in the neck. The only certain way to tell whether a thyroid lump is cancer is by examining the thyroid tissue obtained using a needle or surgery for biopsy. (12 Dec 1998) |
| receptors, thyroid hormone | Proteins, usually found in the nucleus, that specifically bind thyroid hormones and regulate DNA transcription. These proteins, termed c-erba, are activated by hormones and cause differentiation of erythroid progenitor cells which irreversibly lose proliferative potential. Thus c-erba proteins act as growth suppressors. The c-erba proteins are encoded by at least two genes, c-erba alpha and c-erba beta. Each of these has two isoforms. Mutations in the ligand-binding domain of the beta form causes thyroid hormone resistance syndrome. (12 Dec 1998) |
| glandular branches of inferior thyroid artery | <anatomy, artery> Branches of inferior thyroid artery to thyroid and parathyroid glands, anastomosing with branches of superior thyroid artery. Synonym: rami glandulares arteriae thyroideae inferioris. (05 Mar 2000) |
| pharyngeal branch of inferior thyroid artery | <anatomy, artery> Distributed to laryngopharynx. Synonym: rami pharyngeales arteriae thyroideae inferioris. (05 Mar 2000) |
| middle thyroid vein | <anatomy, vein> It passes from the thyroid gland across the common carotid artery with the inferior thyroid arteries to empty into the internal jugular vein. Synonym: vena thyroidea media. (05 Mar 2000) |
| cold thyroid nodule | <radiology> Adenoma (75%), colloid cyst (10%), carcinoma (15%), mnemonic: CATCH PALLM colloid cyst, adenoma, thyroiditis, carcinoma, haematoma, parathyroid adenoma, abscess, lymph node, lymphoma, metastasis thyroid carcinoma, hot thyroid nodule (12 Dec 1998) |
| cornua of thyroid cartilage | See: inferior horn of thyroid cartilage, superior horn of thyroid cartilage. Cornu uteri, the portion of the uterus to which the intramural section of the uterine tube enters on either the right or left. Synonym: uterine horn, horn of uterus. (05 Mar 2000) |
| posterior branch of superior thyroid artery | <anatomy, artery> Branch of superior thyroid artery which descends to supply the apical portion of the ipsilateral lobe of the thyroid, continuing along the posterior border of the gland to anastomose with the inferior thyroid artery. Synonym: ramus posterior arteriae thyroideae superioris. (05 Mar 2000) |
| hormone, thyroid | Chemical substance made by the thyroid gland which is located in the front of the neck. The thyroid gland uses iodine to make thyroid hormones. The two most important thyroid hormones are thyroxine (t4) and triiodothyronine (t3). (12 Dec 1998) |
| hormone, thyroid stimulating | A hormone produced by the pituitary gland (at the base of the brain) that promotes the growth of the thyroid gland (in the neck) and stimulates it to produce its thyroid hormones. Normally, the rate of thyroid hormone production is controlled by the pituitary. When there are insufficient thyroid hormones in the body for normal functioning of the cells, the pituitary releases tsh. Tsh in turn stimulates the thyroid gland to produce more thyroid hormones. In contrast, when there is excessive amount of thyroid hormones, the pituitary gland stops producing tsh. The tsh level then falls and thyroid hormone production is reduced. This mechanism maintains a relatively constant level of thyroid hormones circulating in the blood. This phenomenon is analogous to a thermostat used for temperature regulation in a room: when the temperature rises, the thermostat shuts the heater off and the room temperature falls back to normal. High levels of thyroid hormones cause the tsh level to fall, resulting in no further stimulation of the thyroid gland. In hyperthyroidism, there are continuously elevated levels of the thyroid hormones. Tsh is also known as thyrotropin. (12 Dec 1998) |
