Psoriasis is a long-lasting, noncontagious autoimmune disease characterized by patches of abnormal skin. [4][5] These areas are red, pink, or purple, dry, itchy, and scaly. [8][3] Psoriasis varies in severity from small localized patches to complete body coverage. [3] Injury to the skin can trigger psoriatic skin changes at that spot, which is ...
Auspitz's sign. Auspitz's sign is the appearance of punctate bleeding spots when psoriasis scales are scraped off, named after Heinrich Auspitz. [1] It may also be seen in Darier's disease and actinic keratosis. [2] Importantly, as with many eponymous clinical signs, [3][4] Heinrich Auspitz was not the first to discover the sign named after him.
The adapted PASI index, where the psoriatic area was not converted into an area grade, but was maintained as a continuous variable, also improved the power of the clinical trial. The modified PASI which involves computer-aided area measurement as a continuous variable is named Computer aided psoriasis continuous area and severity score cPcASI.
Skin condition. A skin condition, also known as cutaneous condition, is any medical condition that affects the integumentary system —the organ system that encloses the body and includes skin, nails, and related muscle and glands. [1] The major function of this system is as a barrier against the external environment. [2]
Munro's microabscess. Munro's microabscess is an abscess (collection of neutrophils) in the stratum corneum of the epidermis due to the infiltration of neutrophils from papillary dermis into the epidermal stratum corneum. They are a cardinal sign of psoriasis [1] where they are seen in the hyperkeratotic and parakeratotic areas of the stratum ...
Krupuk kulit (Javanese: rambak or Minangkabau: karupuak jangek, lit: "skin crackers") is a traditional Indonesian cattle skin krupuk (cracker). [2] It is traditionally made from the soft inner skin of cattle ( cow or water buffalo ) which is diced and sun-dried until it hardens and loses most of its water content.
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.

Psoralen plus UVA (PUVA) therapy can be used to treat hyperproliferative skin disorders like psoriasis and certain kinds of skin cancer. [2] Unfortunately, PUVA treatment itself leads to a higher risk of skin cancer. [3] An important use of psoralen is in PUVA treatment for skin problems such as psoriasis and, to a lesser extent, eczema and ...
