Parakeratosis is a mode of keratinization characterized by the retention of nuclei in the stratum corneum. [1] In mucous membranes , parakeratosis is normal. [ 2 ] In the skin, this process leads to the abnormal replacement of annular squames with nucleated cells.
Hyperkeratosis is thickening of the stratum corneum (the outermost layer of the epidermis, or skin), often associated with the presence of an abnormal quantity of keratin, [1] and is usually accompanied by an increase in the granular layer. As the corneum layer normally varies greatly in thickness in different sites, some experience is needed ...
Overall, keratin type 2 plays a crucial role in maintaining the strength and integrity of the skin, hair, and nails. Mutations in keratin genes can lead to various genetic disorders that affect these tissues, such as epidermolysis bullosa simplex , a rare condition characterized by blistering and erosion of the skin and mucous membranes.
