Hypertrophic scar. A hypertrophic scar is a cutaneous condition characterized by deposits of excessive amounts of collagen which gives rise to a raised scar, but not to the degree observed with keloids.

The lack of or decrease in upper motor neuron function leads to loss of inhibition with resultant hyperactivity of lower motor neurons. Different patterns of muscle weakness or hyperactivity ...
The skin weighs an average of four kilograms, covers an area of two square metres, and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. [1] The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin. [3]
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 ...

Steroid-induced skin atrophy is thinning of the skin as a result of prolonged exposure to topical steroids. In people with psoriasis using topical steroids it occurs in up to 5% of people after a year of use. [ 5 ] Intermittent use of topical steroids for atopic dermatitis is safe and does not cause skin thinning. [ 6 ][ 7 ][ 8 ]
Erythroderma is generalized exfoliative dermatitis, which involves 90% or more of the patient's skin. [3] The most common cause of erythroderma is exacerbation of an underlying skin disease, such as Harlequin-type ichthyosis, psoriasis, contact dermatitis, seborrheic dermatitis, lichen planus, pityriasis rubra pilaris or a drug reaction, such as the use of topical steroids.
