Study of idiopathic, exogenous photodermatoses, part II: photobiologic testing.
نویسندگان
چکیده
The second of this series describes the characteristics of 3 types of photobiologic studies: the light test, the photochallenge test, and the photopatch test. We explain how the tests are carried out, the expected results, and their clinical usefulness in various photodermatoses. These tests are needed before attempting to induce adaptation (skin hardening or light tolerance) in the most debilitating cases.

Interactions with ultraviolet radiation (UVR) and chromophores in the skin happen on a daily basis. Photodermatoses, which are abnormal responses to UV exposure, can be classified into subgroups based on pathogenesis. This review will discuss the clinical features, pathogenesis, photobiologic evaluation, prognosis and therapies of the most common photodermatoses.

Photodermatoses are a group of disorders resulting from abnormal cutaneous reactions to solar radiation. They include idiopathic photosensitive disorders, drug or chemical induced photosensitivity reactions, DNA repair-deficiency photodermatoses and photoaggravated dermatoses. The pathophysiology differs in these disorders but photoprotection is the most integral part of their management. Photo...

Photodermatoses are a group of heterogeneous disorders with diverse clinical manifestations and complex aetiology. They can be classified into five general categories including (1) photodermatoses which are secondary to exogenous agents, such as phototoxic and photoallergic reactions, (2) photoexacerbated dermatoses, (3) photodermatoses which are idiopathic such as polymorphic light eruption (P...
