| 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) |

| anaplastic carcinoma of the thyroid | <oncology, tumour> An aggressive form and rare form of thyroid cancer that is one of the most rapidly growing and invasive types of thyroid cancer. It commonly occurs in people over 60 years of age and may cause obstruction of the trachea. The cause is unknown but exposure to radiation may be a factor. Thyroid function tests are usually normal. Hoarse voice, cough and coughing up blood are common symptoms. Examination may reveal nodules in the thyroid gland. Diagnosis is made via biopsy. Treatment is surgical with or without radiation therapy. (27 Sep 1997) |
| 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) |
| giant cell carcinoma of thyroid gland | A rapidly progressive undifferentiated carcinoma observed in the thyroid gland, characterised by numerous, unusually large, anaplastic cells derived from glandular epithelium of the thyroid gland. (05 Mar 2000) |
