“…They used the term “photolocalization” to indicate the preferential distribution of the viral infectious agent in the ultraviolet (UV) light–damaged skin. Other cases have been reported in both children () and adults (). A review of the literature revealed that the photodistributed chickenpox rash is usually characterized by monomorphous elements that appear together and in a simultaneous stage ().…”

It may be worth treating a child seen in the early hours after the onset of a photodistributed chickenpox rash with acyclovir to reduce the severity of the exanthema ().…”

“…Exposure to UV radiation is known to suppress cutaneous cell–mediated immunity and could enhance the spread and increase the severity of the viral infection. Moreover, UV light exposure causes vasodilatation and increases local temperature and capillary permeability in the skin, allowing easier spread of the varicella zoster virus in sun‐exposed areas (). In addition, UV radiation induces damage in epidermal cell membranes, leading to easier spread of typical varicella manifestations in tanned or sun‐exposed areas.…”

Atypical primary varicella rash: Systematic literature review

et al. 2022

View full text Add to dashboard Cite

Aim In previously healthy subjects, primary varicella presents with a distinctive vesicular rash that is more intense on the trunk and head than on the extremities. However, an atypical presentation may occasionally develop. We aimed at systematically assessing the characteristics of cases affected by atypical primary varicella rash. Methods The United States National Library of Medicine, Excerpta Medica and Web of Science databases were reviewed, without date or language restrictions. Articles were eligible if reporting previously healthy and immunocompetent subjects with a primary varicella rash (i.e., a photo‐localised primary varicella or skin inflammation‐associated primary varicella). Results Thirty‐eight reports providing information on 59 cases of atypical primary varicella were identified. Twenty‐four cases (median 8.5 years of age, 19 females) were photo‐localised and 35 (median 4.8 years of age, 15 females) were associated with pre‐existing skin inflammation (including cast occlusion, diaper irritation, operative sites, burns, insect bites, vaccinations or pre‐existing skin disease). The skin rash was monomorphic and without a “starry sky” appearance. Conclusion Primary varicella may have a modified presentation in areas of irritation such as sun exposure or pre‐existing inflammation. There is a need for a wider awareness of these modulators of varicella rash.
