Thyroid nodules are nodules (raised areas of tissue or fluid) which commonly arise within an otherwise normal thyroid gland. [ 1] They may be hyperplastic or tumorous, but only a small percentage of thyroid tumors are malignant. Small, asymptomatic nodules are common, and often go unnoticed. [ 2] Nodules that grow larger or produce symptoms may ...
Toxic multinodular goiter ( TMNG ), also known as multinodular toxic goiter ( MNTG ), is an active multinodular goiter associated with hyperthyroidism . It is a common cause of hyperthyroidism [ 2][ 3] in which there is excess production of thyroid hormones from functionally autonomous thyroid nodules, which do not require stimulation from ...
These nodules grow up at varying rates and secrete thyroid hormone autonomously, thereby suppressing TSH-dependent growth and function in the rest of gland. Inactive nodules in the same goitre can be malignant. [17] Thyroid cancer is identified in 13.7% of the patients operated for multinodular goitre. [18]
Colloid nodules may be initially identified as an unspecified kind of thyroid nodule. Follow-up examinations typically include an ultrasound if it is unclear whether or not there really is a nodule present. Once the presence of a nodule has been confirmed, the determination of the kind of thyroid nodule is done by fine needle aspiration biopsy. [7]
De Quervain's thyroiditis, also known as subacute granulomatous thyroiditis or giant cell thyroiditis, is a self-limiting inflammatory illness of the thyroid gland. [1] De Quervain thyroiditis is characterized by fever, flu-like symptoms, a painful goiter, and neck pain. The disease has a natural history of four phases: thyroid pain ...
Oncology. Thyroid neoplasm is a neoplasm or tumor of the thyroid. It can be a benign tumor such as thyroid adenoma, [ 1] or it can be a malignant neoplasm ( thyroid cancer ), such as papillary, follicular, medullary or anaplastic thyroid cancer. [ 2] Most patients are 25 to 65 years of age when first diagnosed; women are more affected than men ...
Subacute lymphocytic thyroiditis, also called painless or silent thyroiditis, occurs in individuals with underlying autoimmune disease or after pregnancy. [ 2][ 4][ 5] It is considered to be a variant of Hashimoto's thyroiditis. When subacute lymphocytic thyroiditis occurs up to 12 months postpartum, it is called postpartum thyroiditis.
Histopathology of NIFTP, H&E stain. [1]Noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) is an indolent thyroid tumor that was previously classified as an encapsulated follicular variant of papillary thyroid carcinoma, [2] necessitating a new classification as it was recognized that encapsulated tumors without invasion have an indolent behavior, [2] and may ...
