“…According to the results of the photopatch series in Southern European countries, drugs are by far the main cause of exogenous photoallergy, whereas in the Northern countries sunscreens occupy the first rank as photosensitizers [62,[64][65][66]. This may be due to different prescription habits or because NSAIDs, the main drugs responsible for positive photopatch tests, were not regularly included in most photopatch test series.…”

“…Other UVB filters, namely the salycilates (octylsalycilate and homosalate) and octocrylene are seldom reported to cause allergic or photoallergic contact dermatitis [75,76], except in an Italian study where octocrylene was the most frequent UV filter responsible for photopatch test reactions [66].…”

“…Systemically, antimicrobials, particularly tetracyclines, fluorquinolones, sulfonamides, and some antifungals (voriconazole, griseofulvin), NSAIDs, phe nothiazines, and cardiovascular drugs are mainly re spon sible for photosensitivity, whereas after topical application, NSAIDs are by far the most frequent cause [62,[64][65][66].…”

“…In most reports, the main topical photosensitizers are the UV filters [3,60,61], which represent 56-80% of the cases diagnosed by photopatch testing [3,[62][63][64]. Furocoumarins from plants are an important source of photosensitivity, mainly in more sunny countries, and drugs are, by far, the most frequent photosensitizers in Southern Europe [62,[64][65][66].…”

“…Cinnamates, namely isoamyl-p-methoxycinnamate and ethylhexyl-p-methoxycinnamate, and 4-methylbenzylidene camphor, phenylbenzimidazole sulfonic acid, drometrizole trisiloxane (Mexoryl XL) and octyl dimethyl PABA (Padimate O) are also regularly responsible for cases of photoallergy [3,4,62,64,66,67]. Other UVB filters, namely the salycilates (octylsalycilate and homosalate) and octocrylene are seldom reported to cause allergic or photoallergic contact dermatitis [75,76], except in an Italian study where octocrylene was the most frequent UV filter responsible for photopatch test reactions [66].…”

Background: Octocrylene is a new emerging photoallergen. We report and discuss 50 cases of photoallergic contact dermatitis from octocrylene use and/or positive photopatch test reactions to this UV filter and draw attention to the unexpected association in adults with a history of photoallergic contact dermatitis from ketoprofen.Observations: Patients were divided in 3 groups: group A comprised 11 children; group B, 28 adults with a history of photoallergy from sunscreen products; and group C, 14 adults systematically tested with octocrylene because of a history of photoallergy from ketoprofen. All patients but 3 in group C had positive test reactions to octocrylene. Ten of 11 children in group A and 9 of 28 adults in group B had positive patch test reactions to octocrylene. One child in group A, the other 19 adults in group B, and 11 of 14 adults in group C had positive pho-

Photosensitive skin reactions occur when human skin abnormally reacts to ultraviolet radiation or visible light. The forms of photosensitivity are phototoxity and photoallergy. Phototoxic disorders have a high incidence, whereas photoallergic reactions are much less frequent in the human population. Several hundred substances, chemicals or drugs may invoke phototoxic or photoallergic reactions. In order to avoid photosensitive reactions it is essential to determine the photosensitizing properties of such substances before drugs are introduced in therapy or products made available on the market. This chapter reviews the mechanisms of photosensitization, explains the most important differences between phototoxic and photoallergic reactions, summarizes the most common photosensitzers and presents the clinical features and diagnostic procedures of phototoxic and photoallergic reactions.
