Changes in the degree of keratinisation
or the keratinisation
status of ODT epithelial tissue due to chemical irritants and chronic trauma are widely reported.
This half-and-half appearance can often also occur in people with uraemia (a toxic condition resulting from kidney disease in which there is retention in the bloodstream of waste products normally excreted in the urine) and after chemotherapy discussed later as when there is defective keratinisation
due to cell arrest in the nail.
Histopathological examination revealed extensive proliferation of squamous cells forming concentric layers with Keratinisation
at the centre, giving the appearance of a typical epithelial pearl (Fig.
WDSCC showed abundant intercellular bridging, cytoplasmic keratinisation
and keratin pearls, nuclear pleomorphism was minimal and mitotic figures were <2/hpf.
With age, a lot of changes occur within the meibomian glands including: narrowing/ plugging of the orifices; vascularity; keratinisation
; appearance of telangiectasia; lid margin rounding; increased prevalence of blepharitis; and reduction in the number of glands secreting oil.
Porokeratosis is a morphologically distinct disorder of keratinisation
. It is characterised clinically by hyperkeratotic papules or plaques with raised and advancing edge, which histologically corresponds to a column of parakeratotic cells.
Squamous pearls and individual cell keratinisation
was also noted.
In acanthomatous type the central area of follicles often undergo squamous metaplasia with the development of intercellular bridges and keratinisation
. This can be florid occasionally to the point where so much of the lesion is replaced by squamous cells that it may resemble a squamous cell carcinoma.
Entre la vitamine B3 qui accroEt la circulation du sang dans les racines, la B5 qui aide a la croissance du cheveu et la B6 indispensable au processus de keratinisation
