FNA smears in these patients showed moderate to severe background colloid and lymphocytes infiltrating
follicular cell clusters and Hurthle cells (Figure 3(a)).
The evaluation under light microscopy revealed that chronic sevoflurane exposure led to
follicular cell oedema, degeneration, congestion and bleeding in the ovaries of rats (Figure-1B-1F).
Squamous
follicular cells in vitellogenic oocytes of L.
Of all FNA samples deriving from
follicular cells 31 (6.7%) were positive for mutations (n=24) or gene fusions (n=7).
The FTC and PTC are well-differentiated carcinomas, which are originated in the
follicular cells [48,49].
[sup][10] According to the consensus reached that conference, PDTC is a malignant tumor that originates from thyroid
follicular cells, and trabecular, island, and/or solid growth patterns are necessary for diagnosis.
Case 1: Cytological smears showed abundant colloid with moderate number of
follicular cells arranged in sheets and occasional macrophages favoring the diagnosis of nodular colloid goiter.
Electronmicrographs revealed disintegration and destruction in
follicular cells and mitochondria in females.
However, the oxidation of iodine requires hydrogen peroxide synthesized outside the thyroid
follicular cell at the apical border catalyzed by the thyroid complex.
In the 45 newly diagnosed with the
follicular cell type, some are not being treated at all, particularly those with limited disease; in advanced patients, combination therapy is common.
* Tazarotene, another synthetic retinoid applied as a gel or cream, acts on the
follicular cell cycle by a biochemical pathway different from that of tretinoin.
