This number of the Revista da Sociedade Portuguesa de Dermatologia e Venereologia contains two articles dedicated to idiopathic photodermatoses, for which autoimmune reactions to an unknown endogenous chromophore are suspected to be involved – polymorphous light eruption, actinic prurigo, hydroa vacciniforme, chronic actinic dermatitis, and solar urticarial.1,2 Many of these and other photodermatoses have a very clear clinical presentation, while others may mimic allergic contact dermatitis…

TLDR
Chronic actinic dermatitis is a contact dermatitis-like reaction apparently against sunlight-induced endogenous cutaneous antigen, and is most common in temperate climates, and in elderly men of any race, but apparently does not demonstrate familial incidence.
Contact and photocontact allergy to ketoprofen. The Belgian experience
TLDR
A prospective, open patch and photopatch test study in 20 patients suspected of KP dermatitis found a high frequency of contact allergy to fragrance mix andDermatologists should be aware of the severity of photoallergic reactions to KP and the risk of cross‐sensitization.
Contact and photocontact allergy to ketoprofen: clinical and experimental study
TLDR
Although ketoprofen appears not to be a sensitizing agent in human volunteers, the fact that photosensitization to this drug seems to be quite common after topical use suggests that there are some local or individual factors facilitating the development of allergy.
Contact and photocontact sensitivity to sunscreens
TLDR
Patch tests, with the GIRDCA standard and agriculture series confirmed the already-known positivity to potassium dichromate 0.5% pet.
The UV filter tinosorb M, containing decyl glucoside, is a frequent cause of allergic contact dermatitis.
TLDR
A retrospective study to evaluate the frequency of ACD from Tinosorb M, patients’ characteristics, and responsible allergens, which found that recurrent dermatitis recurred frequently despite topical corticosteroids.
Serious photocontact dermatitis induced by topical ketoprofen depends on the formulation
TLDR
Photosensitisation to ketoprofen can be mitigated by a patch formulation, which protects the drug from direct UV exposure during skin application, and reduces the formation of even more photoallergic photodegradation products.
Decyl glucoside contact allergy from a sunscreen product
TLDR
A 61-year-old man presented with a solitary ulcerated plaque below the right eye, which had been gradually increasing in size for 8 months, and was referred for patch tests, which demonstrated a strongly positive (+++) reaction to nickel.
Adverse reactions to sunscreen agents: epidemiology, responsible irritants and allergens, clinical characteristics, and management.
TLDR
This review focuses on the 36 most common UV filters in commercial and historical use, and the benzophenones and dibenzoylmethanes are the most commonly implicated UV filters causing allergic and photoallergic contact dermatitis (PACD) reactions.
Allergic contact cheilitis caused by polysilicone‐15 (Parsol® SLX) in a lipcare balm
A 14-year-old girl with a history of atopic dermatitis presented with acute cheilitis of 2 months’ duration. She had redness of her lips with dryness, extending around to the peri-oral skin. She had
