Hyperkeratosis is a thickening of the outer layer of skin, producing a tough, often dry area that may be discolored.Hyperkeratosis can trigger localized hyperpigmentation in the stratum corneum of the epidermis, along with an increased production of protective keratin.eratin is a protein that is part of the structural matrix of the skin (along with collagen and elastin), providing strength and water resistance to the outer layer. Hyperkeratosis is exacerbated with continued irritation and dehydration of the areas.
Hyperkeratosis can also be caused by B-Raf inhibitor drugs such as Vemurafenib and Dabrafenib. Epidermolytic hyperkeratosis (also known as Bullous congenital ichthyosiform erythroderma, Bullous ichthyosiform erythroderma, or bullous congenital ichthyosiform erythroderma Brocq) is a rare skin disease in the ichthyosis family affecting around 1 in 250,000 people. 2  It involves the clumping of keratin filaments.
