Polymorphous light eruption (PLE) presents with itchy red small bumps on sun-exposed skin, particularly face, neck, forearms and legs. [1] It generally appears 30 minutes to a few hours after sun exposure and may last between one and 14 days. [ 3 ]
Especially common in women, but present in both sexes, polymorphous light eruption is a rash that commonly occurs in the first couple of days or weeks of summer, when the skin is newly exposed to ...
Acne aestivalis also called as acne mallorca, is a special kind of polymorphous light eruption induced by ultra violet A radiation. This condition is said to be seasonal, usually affecting people in springtime and goes away in autumn when there is less sun light. This photo induced skin reaction leads to a mono-morphous eruption that consists ...
An example of primary photodermatoses is Polymorphous light eruption. Polymorphous light eruption is the most common type of photodermatoses. It is most likely due to an abnormal immune system reaction to the sun. Polymorphous light eruption occurs in approximately 10 to 20 percent [3] of otherwise healthy individuals, so it is a relatively common
Actinic prurigo is a rare sunlight-induced, pruritic, papular, or nodular skin eruption. Some medical experts use the term actinic prurigo to denote a rare photodermatosis that develops in childhood and is chronic and persistent; this rare photodermatosis, associated with the human leukocyte antigen HLA-DR4, is often called "Familial polymorphous light eruption of American Indians" or ...
Polymorphous light eruption is a condition affecting the skin thought to be caused by an adverse reaction to ultraviolet light. Its prevalence across Europe is 10-20% of the population. Artificial light sources may provoke the condition, and compact fluorescent light have been shown to produce an eruption.
Solar urticaria is an immunoglobulin E-mediated hypersensitivity that can be introduced through primary or secondary factors, or induced by exogenous photosensitization. [15] [16] Primary SU is believed to be a type I hypersensitivity (a mild to severe reaction to an antigen including anaphylaxis) in which an antigen, or substance provoking an immune response, is "induced by UV or visible ...
Reports say that this volcanic eruption could trigger an ice age from the sheet of ash that not even the sun could stand a chance of penetrating. 'High threat' supervolcano could bring about an ...
