Thyroid follicular cells (also called thyroid epithelial cells or thyrocytes [1]) are the major cell type in the thyroid gland, and are responsible for the production and secretion of the thyroid hormones thyroxine (T 4) and triiodothyronine (T 3).
Follicular dendritic cell sarcoma (FDCS) is an extremely rare neoplasm.While the existence of FDC tumors was predicted by Lennert in 1978, the tumor wasn't fully recognized as its own cancer until 1986 after characterization by Monda et al. [1] [2] It accounts for only 0.4% of soft tissue sarcomas, but has significant recurrent and metastatic potential and is considered an intermediate grade ...
Follicular thyroid cancer accounts for 15% of thyroid cancer and occurs more commonly in women over 50 years of age. Thyroglobulin (Tg) can be used as a tumor marker for well-differentiated follicular thyroid cancer. Thyroid follicular cells are the thyroid cells responsible for the production and secretion of thyroid hormones.
The latter is a relatively rare form of differentiated thyroid cancer, accounting for only 3-10% of all differentiated thyroid cancers, [7] and was formerly considered a subtype of follicular thyroid cancer. The mitochondrial DNA of Hürthle cell carcinoma contain somatic mutations. [6] Hürthle cell carcinomas consists of at least 75% Hürthle ...
- Follicular dendritic cells have round nuclei, centrally located nucleoli, bland and dispersed chromatin, and flattening of adjacent nuclear membrane. Follicular dendritic cells ( FDC ) are cells of the immune system found in primary and secondary lymph follicles ( lymph nodes ) of the B cell areas of the lymphoid tissue .
Hyalinizing trabecular tumor (d–f) is composed of trabeculae of elongated or polygonal cells admixed with abundant amounts of hyaline material negative for amyloid and positive for type IV collagen (f); Ki-67 is characteristically expressed in the cell membrane but not in the nuclei of the tumor cells (e). Follicular adenoma with signet ring ...
Follicular hyperplasia (FH) is a type of lymphoid hyperplasia and is classified as a lymphadenopathy, which means a disease of the lymph nodes. It is caused by a stimulation of the B cell compartment and by abnormal cell growth of secondary follicles. This typically occurs in the cortex without disrupting the lymph node capsule. [1]
Follicular cell may refer to: Thyroid follicular cell, found in the thyroid gland; Granulosa cell, found in the follicles around oocytes; Follicular dendritic cell ...
