fotodermatoser

Fotodermatoser, also known as photodermatosis, is a group of skin conditions that are triggered by exposure to sunlight or ultraviolet (UV) light. These conditions are characterized by the development of skin lesions, such as rashes, blisters, or patches, in response to UV radiation. The term "fotodermatoser" is derived from the Greek words "photos" meaning light, and "dermatos" meaning skin.

The exact cause of photodermatosis is not fully understood, but it is believed to involve a combination of genetic and environmental factors. Individuals with certain genetic predispositions may be more susceptible to developing photodermatosis. Environmental factors, such as prolonged sun exposure, can also play a role in the development of these conditions.

Photodermatosis can manifest in various forms, including polymorphic light eruption (PLE), solar urticaria, and solar urticarial-like eruption. PLE is the most common form, characterized by the development of red, itchy patches on the skin after sun exposure. Solar urticaria presents as a wheal-and-flare reaction, with hives and itching, while solar urticarial-like eruption is similar to solar urticaria but without the hives.

Treatment for photodermatosis typically involves avoiding further sun exposure and using topical corticosteroids to reduce inflammation and itching. In some cases, photoprotective measures, such as wearing protective clothing and using sunscreen, may be recommended to prevent future episodes. If symptoms are severe or persistent, a healthcare professional may be consulted for further evaluation and treatment options.
