38,39) Owing to the patchy and multifocal nuclear changes in FVPTC, which are commonly interspersed with benign-looking thyroid follicles
, there is a tendency to diagnose these as multiple foci of papillary microcarcinoma arising within an FA or HCN.
latirostris, where this amine was detected on the base of the follicular epithelium, the location of the parafollicular cells, as well as between the thyroid follicles
The cells of these structures may originate from the cells of paramesonephricus ducts, salivary glands, breast tissue, thyroid follicles
, squamous epithelium or mesothelium.
The resulting iodothyronines are then reversibly combined with the storage protein, thyroglobulin, within the lumen of each of the thyroid follicles
(Leatherland 1988, 1993).
Destruction of thyroid follicles
by these immune cells is the main mechanism of pathogenesis in HT .
Thyroidal sympathetic adrenergic nerve terminals were found as single terminals between, and sometimes around, thyroid follicles
At these high intakes, uptake of iodine into the thyroid gland appears to be inhibited, resulting in reduced synthesis of thyroxine and elevated secretion of TSH, which stimulates the thyroid follicles
to enlarge and multiply, producing a goitre.
TGDC is associated with a tract, thyroid follicles
, and attachment to the hyoid bone.
Transient thyrotoxicosis usually occurs 1 to 3 months after delivery, and is caused by the release of stored hormones from the inflammatory destruction of the thyroid follicles
Sections of histopathological examination showed thyroid follicles
separated by mature adipose tissue in majority of the area and focal amyloid deposition.
This gland consists of thousands of thyroid follicles
, vesicular endocrine glands coated by simple cuboidal epithelium and C cells (or parafollicular cells) [4,5,7].
