Skin biopsy can also be performed which typically shows a psoriasiform reaction pattern characterized by epidermal hyperplasia with elongation of the rete ridges. [24] There is no firm evidence regarding the best management for guttate psoriasis; however, first-line therapy for mild guttate psoriasis typically includes topical corticosteroids.
Ichthyosis (also named fish scale disease) [1] is a family of genetic skin disorders characterized by dry, thickened, scaly skin. [2] The more than 20 types of ichthyosis range in severity of symptoms, outward appearance, underlying genetic cause and mode of inheritance (e.g., dominant, recessive, autosomal or X-linked). [3]
Ichthyosis vulgaris is the most common type within the ichthyoses, a diverse group of inherited skin disorders characterized by the way the skin produces keratin. These conditions all share the common trait of causing generalized skin scaling, which can range in its intensity.
The skin weighs an average of 4 kg (8.8 lb), covers an area of about 2 m 2 (22 sq ft), 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 nonhairy skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin. [16]
X-linked ichthyosis (abbreviated XLI) is a skin condition caused by the hereditary deficiency of the steroid sulfatase (STS) enzyme that affects 1 in 2000 to 1 in 6000 males. [2] XLI manifests with dry, scaly skin [ 3 ] and is due to deletions [ 4 ] [ 5 ] or mutations [ 6 ] in the STS gene.
In short, melasma is a chronic skin condition that appears as darkened areas on the face due to an overproduction of melanin, says Gina Charles, MO, a family physician specializing in skincare. It ...
People with this condition are extremely sensitive to changes in temperature due to their hard, cracked skin, which prevents normal heat loss. The skin also restricts respiration, which impedes the chest wall from expanding and drawing in enough air. This can lead to hypoventilation and respiratory failure.
Hidradenitis suppurativa is a chronic inflammatory skin condition that impacts up to two percent of people in the U.S. (That's roughly 6.5 million people.) But while the condition can be ...
