It is recommended that follicular cell
carcinoma should be considered in the differential diagnosis of bone cyst in any patient with history of FTC even years after primary therapy.

origin with high grade features (high mitotic rate/tumornecrosis): a clinicopathologic and molecular study," Human Pathology, vol.
The only case of HT with carcinoma showed evidence of increased lymphocytes on background, occasional thyroid follicular cell
cluster infiltrated by lymphocytes, and many scattered large atypical cells having large nuclei and intranuclear inclusion (Figures 4(a) and 4(b) arrow).
Normal ovarian architecture was defined as grade 0; mild oedema, mild follicular cell
degradation, mild vascular congestion, no haemorrhage and no leukocyte infiltration was grade 1; moderate oedema, moderate follicular cell
degradation, moderate vascular congestion, no haemorrhage and no leukocyte infiltration was grade 2; severe oedema, severe follicular cell
degradation, severe vascular congestion, minimal haemorrhage and minimal leukocyte infiltration as grade 3, and severe oedema, severe follicular cell
degradation, severe vascular congestion, haemorrhage and leukocyte infiltration as grade 4,12,13
Neutral glycoproteins were detected in the follicular cells
, pellucid zone, cortical alveoli and yolk globules of the six species studied due to the positive reaction to the PAS technique (Fig.

origin," Archives of Pathology & Laboratory Medicine, vol.
Using genomic, transcriptomic and proteomic assays on thyroid cell cultures (PC Cl 3 (PC) and follicular cell
line--derived from 18-month-old Fischer rats on Matrigel[R]--, they demonstrated that RET/ PTC3-RAS-BRAF axis acts synergistically to alter thyroid cells (in vitro and in vivo) into an invasive phenotype.
The concluding sections describe available treatments including hair transplant, hair ocloningo by follicular cell
implantation, autologous stem cell therapies, adjuvants such as prostheses and dermopigmentation, and cosmetology of cleansing and conditioning agents.
Malignant tumors of thyroid follicular cell
origin are categorized as well-differentiated thyroid carcinoma (WDTC), consisting the majority of papillary thyroid carcinoma (PTC) and follicular thyroid carcinoma, poorly differentiated thyroid carcinoma (PDTC), and undifferentiated/anaplastic thyroid carcinoma (ATC).
There is the appearance of a continuous acidophilic layer, the vitelline membrane, which is surrounded by a layer of follicular cells
. The appearance of the vitelline membrane and follicular cell
layer assists the identification of this developmental stage, as reported for Hypostomus strigaticeps (Takahashi et al., 2008).
