Photosensitive dermatoses in paediatric practice

Abstract

Photodermatoses represent a heterogeneous group of disorders characterized by the development of pathological skin reaction to solar radiation. The development or intensification of inflammatory skin reaction after exposure to ultraviolet or electromagnetic spectrum that is visible to the human eye is a distinctive feature of all photosensitive photodermatoses. Although photodermatoses are less common in children than in adults, they are often associated with genetic or congenital metabolic disorders, and may also point to diffuse connective tissue diseases. Paediatric photodermatoses are often the result of genetic or congenital metabolic disorders, and may also indicate diffuse connective tissue diseases. The epidemiological studies have showed that the global prevalence of photodermatoses diagnosed with photopatch tests is above or equal to 5.7%. The authors presented a modern classification of photosensitive dermatoses according to the etiological factor. The article provides up-to-date information about photosensitive dermatoses, including statistical epidemiological data, pathogenesis features, and also emphasis is placed on the issues of the quality of life of children and their parents. The authors described the clinical presentations of the most common paediatric photosensitive dermatoses and the basic principles of their therapy. Among topical glucocorticosteroids, methylprednisolone aceponate has proven itself in the treatment of paediatric photodermatoses as it has not only a pronounced anti-inflammatory effect, but also is easy-to-use. The timely diagnosis of paediatric photosensitivity will help to minimize the development of complications associated with delayed treatment and insufficient prevention (photoprotection).
