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.
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 ...
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.
The use of rituximab has been established for the treatment of B-cell–derived hematologic malignancies, including follicular lymphoma (FL) and diffuse large B-cell lymphoma (DLBCL). [ 7 ] In addition to cure-directed treatment, people can benefit from self-care to manage symptoms.
Diagnosis is often based on ultrasound and fine needle aspiration. [1] Screening people without symptoms and at normal risk for the disease is not recommended. [10] [11] Treatment options may include surgery, radiation therapy including radioactive iodine, chemotherapy, thyroid hormone, targeted therapy, and watchful waiting. [1]
Follow-up of 33 patients with ISFL over a period of 12 to 132 months diagnosed FL with times of progression of 15 and 29 months in two (6% of all followed) patients. Studies on the development of other types of lymphoid malignancies in ISFL are based primarily on case reports. [ 2 ]
Thyroid follicular adenoma ranges in diameter from 3 cm on an average, but sometimes is larger (up to 10 cm) or smaller. The typical thyroid adenoma is solitary, spherical and encapsulated lesion that is well demarcated from the surrounding parenchyma.
In situ follicular lymphoma is an accumulation of monoclonal B cells (i.e. cells descendent from a single ancestral cell) in the germinal centers of lymphoid tissue. These cells commonly bear a pathological genomic abnormality, i.e. a translocation between position 32 on the long (i.e. "q") arm of chromosome 14 and position 21 on chromosome 18's q arm.
