Label	Id	Description
Thymus Hyperplasia	D013952	[Enlargement of the thymus. A condition described in the late 1940's and 1950's as pathological thymic hypertrophy was status thymolymphaticus and was treated with radiotherapy. Unnecessary removal of the thymus was also practiced. It later became apparent that the thymus undergoes normal physiological hypertrophy, reaching a maximum at puberty and involuting thereafter. The concept of status thymolymphaticus has been abandoned. Thymus hyperplasia is present in two thirds of all patients with myasthenia gravis. (From Segen, Dictionary of Modern Medicine, 1992; Cecil Textbook of Medicine, 19th ed, p1486)]
Thymus Neoplasms	D013953	[Tumors or cancer of the THYMUS GLAND.]
Thyroglossal Cyst	D013955	[A cyst in the neck caused by persistence of portions of, or by lack of closure of, the primitive thyroglossal duct. (Dorland, 27th ed)]
Thyroid Cancer, Papillary	D000077273	[An ADENOCARCINOMA that originates from follicular cells of the THYROID GLAND and accounts for the majority of THYROID CANCER cases. Cells exhibit enlarged, oval, or elongated morphologies with clear, round, nuclei. Fusions of RET, NTRK1, TPM3, and PCM1 genes are associated with this cancer.]
Thyroid Carcinoma, Anaplastic	D065646	[An aggressive THYROID GLAND malignancy which generally occurs in IODINE-deficient areas in people with previous thyroid pathology such as GOITER. It is associated with CELL DEDIFFERENTIATION of THYROID CARCINOMA (e.g., FOLLICULAR THYROID CARCINOMA; PAPILLARY THYROID CANCER). Typical initial presentation is a rapidly growing neck mass which upon metastasis is associated with DYSPHAGIA; NECK PAIN; bone pain; DYSPNEA; and NEUROLOGIC DEFICITS.]
Thyroid Crisis	D013958	[A dangerous life-threatening hypermetabolic condition characterized by high FEVER and dysfunction of the cardiovascular, the nervous, and the gastrointestinal systems.]
Thyroid Diseases	D013959	[Pathological processes involving the THYROID GLAND.]
Thyroid Dysgenesis	D050033	[Defective development of the THYROID GLAND. This concept includes thyroid agenesis (aplasia), hypoplasia, or an ectopic gland. Clinical signs usually are those of CONGENITAL HYPOTHYROIDISM.]
Thyroid Hormone Resistance Syndrome	D018382	[An inherited autosomal recessive trait, characterized by peripheral resistance to THYROID HORMONES and the resulting elevation in serum levels of THYROXINE and TRIIODOTHYRONINE. This syndrome is caused by mutations of gene THRB encoding the THYROID HORMONE RECEPTORS BETA in target cells. HYPOTHYROIDISM in these patients is partly overcome by the increased thyroid hormone levels.]
Thyroid Neoplasms	D013964	[Tumors or cancer of the THYROID GLAND.]
Thyroid Nodule	D016606	[A small circumscribed mass in the THYROID GLAND that can be of neoplastic growth or non-neoplastic abnormality. It lacks a well-defined capsule or glandular architecture. Thyroid nodules are often benign but can be malignant. The growth of nodules can lead to a multinodular goiter (GOITER, NODULAR).]
Thyroiditis	D013966	[Inflammatory diseases of the THYROID GLAND. Thyroiditis can be classified into acute (THYROIDITIS, SUPPURATIVE), subacute (granulomatous and lymphocytic), chronic fibrous (Riedel's), chronic lymphocytic (HASHIMOTO DISEASE), transient (POSTPARTUM THYROIDITIS), and other AUTOIMMUNE THYROIDITIS subtypes.]
Thyroiditis, Autoimmune	D013967	[Inflammatory disease of the THYROID GLAND due to autoimmune responses leading to lymphocytic infiltration of the gland. It is characterized by the presence of circulating thyroid antigen-specific T-CELLS and thyroid AUTOANTIBODIES. The clinical signs can range from HYPOTHYROIDISM to THYROTOXICOSIS depending on the type of autoimmune thyroiditis.]
Thyroiditis, Subacute	D013968	[Spontaneously remitting inflammatory condition of the THYROID GLAND, characterized by FEVER; MUSCLE WEAKNESS; SORE THROAT; severe thyroid PAIN; and an enlarged damaged gland containing GIANT CELLS. The disease frequently follows a viral infection.]
Thyroiditis, Suppurative	D013969	[Acute inflammatory disease of the THYROID GLAND due to infections by BACTERIA; FUNGI; or other microorganisms. Symptoms include tender swelling, FEVER, and often with LEUKOCYTOSIS.]
Thyrotoxicosis	D013971	[A hypermetabolic syndrome caused by excess THYROID HORMONES which may come from endogenous or exogenous sources. The endogenous source of hormone may be thyroid HYPERPLASIA; THYROID NEOPLASMS; or hormone-producing extrathyroidal tissue. Thyrotoxicosis is characterized by NERVOUSNESS; TACHYCARDIA; FATIGUE; WEIGHT LOSS; heat intolerance; and excessive SWEATING.]
Tibial Fractures	D013978	[Fractures of the TIBIA.]
Tibial Meniscus Injuries	D000070600	[Injuries to the TIBIAL MENISCUS of the leg.]
Tibial Neuropathy	D020429	[Disease of the TIBIAL NERVE (also referred to as the posterior tibial nerve). The most commonly associated condition is the TARSAL TUNNEL SYNDROME. However, LEG INJURIES; ISCHEMIA; and inflammatory conditions (e.g., COLLAGEN DISEASES) may also affect the nerve. Clinical features include PARALYSIS of plantar flexion, ankle inversion and toe flexion as well as loss of sensation over the sole of the foot. (From Joynt, Clinical Neurology, 1995, Ch51, p32)]
Tic Disorders	D013981	[Disorders characterized by recurrent TICS that may interfere with speech and other activities. Tics are sudden, rapid, nonrhythmic, stereotyped motor movements or vocalizations which may be exacerbated by stress and are generally attenuated during absorbing activities. Tic disorders are distinguished from conditions which feature other types of abnormal movements that may accompany another another condition. (From DSM-IV, 1994)]
