Thyroid gland follicular carcinoma
is a malignant epithelial neoplasm of follicular cell differentiation that exhibits capsular and/or lymphovascular invasion while lacking the nuclear features of thyroid papillary carcinoma.
The test consists of a panel comprised of eight genes associated with papillary and follicular carcinoma
, the two most common forms of thyroid malignancies.
A referral for operative exploration is recommended in such cases; usually, a hemi-thyroidectomy or lobectomy is performed, followed by histologic examination for capsular and vascular invasion to distinguish between follicular adenoma and follicular carcinoma
A rare morphologic subtype of RCC, thyroidlike follicular carcinoma
of the kidney, is characterized by a follicular, partially cystic, architectural pattern mimicking metastatic thyroid carcinoma.
This case describes a patient with thyroid cancer who suffered complete superior vena cava obstruction as a result of follicular carcinoma
metastasis into the SVC, creating a massive venous thrombus.
RAS point mutations and PAX8-PPAR[gamma] rearrangement in thyroid tumors: evidence for distinct molecular pathways in thyroid follicular carcinoma
Also, the absence of well differentiated regions, such as papillary or follicular carcinoma
in angiosarcomas, in contrast to anaplastic carcinomas, is another characteristic that is used for differentiation.
was diagnosed in 15 patients, and the balance had papillary carcinoma of the thyroid.
All patients who have undergone a total or near-total thyroidectomy for a papillary or follicular carcinoma
larger than 1 to 1.
14 cases were diagnosed cytologically as benign follicular cells, histopathologically were diagnosed as follows: 2 cases microfollicular adenoma, 2 cases as lymphocytic thyroiditis 8 cases as diffuse hyperplaslic thyroid tissue and 2 cases as follicular carcinoma
two cases were diagnosed cytologically as undifferentiated malignant cells histopathologically was diagnosed as malignant lymphoma.
Papillary carcinoma was the pathology in 14 of 17 cases; follicular carcinoma
was identified in 2 cases, and medullary carcinoma in 1.
Intended for both pathologists and endocrinologists, this reference collects the different approaches required to manage papillary carcinoma, follicular carcinoma
, medullary thyroid carcinoma, thyroid lymphomas, and anaplastic cancers.
