“…It was agreed that phototesting should ideally be undertaken on clear skin and that topical corticosteroids and systemic immunosuppressants should be avoided where feasible. Topical corticosteroids can suppress UV‐induced erythema and prednisolone, even at 10mg orally, may suppress CAD photosensitivity and is best avoided for at least a week prior to testing 12–15 . The effects of other immunosuppressants on phototesting are unknown, although it seems prudent to avoid immunosuppression where possible.…”

Background Photodiagnostic investigations are essential for the accurate diagnosis of abnormal cutaneous photosensitivity and provide important information for the management of patients with photodermatoses (cutaneous photosensitivity disorders). Although photodiagnosis has been undertaken since the early 1970s, specialist services in the United Kingdom (UK) and Republic of Ireland are limited and there is no formal guidance on diagnostic approach. Indeed, there is a limited literature in this area of methodology and diagnostic practice. Objectives The primary objective was to undertake a British Photodermatology Group Workshop to review the role and activities of specialist centres in the UK and Republic of Ireland in order to ascertain whether there were consensus practices. Secondary objectives were to identify key priorities for service, training and research. Methods An initial detailed survey review of current activities was undertaken prior to the Workshop and data from this survey were used to inform discussion at the Workshop, which was attended by key photodermatology experts from the UK and Republic of Ireland. Results/Conclusions We have undertaken a detailed review of current Photodiagnostic Services in the UK and Republic of Ireland and report on our findings from the 12 centres and we have identified key areas of consensus practice. This is an important step in the process of standardising and optimising procedures and protocols and defining minimum clinical standards for photodiagnostic investigations, which are of such diagnostic importance in Dermatology.

The photodermatoses are a diverse group of diseases, some of which, such as polymorphic light eruption, are very common and others, such as hydroa vacciniforme or xeroderma pigmentosum, are rare. It is essential not to miss the diagnosis of these conditions and referral to a specialist photodiagnostic centre is advised for many patients. Management depends on the diagnosis but includes prevention and disease suppression. Photoprotection is a mainstay approach for the photodermatoses but is often not sufficient for disease control. Desensitization using photo(chemo)therapy regimens may be feasible and systemic therapies are sometimes needed. Photosensitivity, particularly if chronic and severe, can be associated with significant psychological morbidity, which must be considered. Awareness of the possibility of vitamin D deficiency is also required.

The photodermatoses are a diverse group of conditions in which abnormal responses to light exposure are the hallmark. Photodiagnostic investigations through a specialist unit may be essential to ensure accurate diagnosis and management, and this chapter explores the nature of the photodermatoses and the photodiagnostic techniques that can be applied. Management approaches include early diagnosis, prevention and disease suppression, and awareness of the significant adverse impact on well‐being and psychological health that can occur with photosensitivity. Photoprotection is a mainstay approach for the photodermatoses but is often not sufficient alone for disease control. Desensitisation through natural hardening or light‐based therapies may be feasible, although systemic immunosuppressants and immunomodulators may be required. Awareness of the possibility of vitamin D deficiency is also necessary. This chapter will cover these approaches in detail.
