Background: The phototest is used to confirm the diagnosis of polymorphous light eruption and to evaluate the different treatments. The different light sources in the different countries explains the lack of standardization. In France, we use a polychromatic source emitting a radiation close to the solar spectrum. Read More

Background/purpose: Polymorphous light eruption (PLE) heterogeneity has been postulated, but the existence of benign summer light eruption (BSLE) is controversial. We studied the prevalence of the clinical patterns, criteria distinguishing BSLE from PLE, and diagnostic usefulness of phototest.
Methods: Five Italian Photodermatology Centres recruited retrospectively 346 patients with typical clinical history and/or presentation of PLE. Read More

Background: Diagnosis of polymorphic light eruption (PLE) is based on the patient's history, the morphology of the lesions and the results of phototesting. Skin lesions of PLE can be provoked by repetitive UVB or UVA irradiation. However, about 20% of the patients with PLE have negative phototests. Read More

Unlabelled: INTRODUCTION This case report of benign summer light eruption emphasizes the importance of phototests in the diagnosis of photosensitive dermatoses.
Case Report: A 25-year-old man, phototype II, had experienced a pruriginous papulovesicular erythematous eruption of the axillary and inguinal regions each summer for 12 years. A high-dose UV phototest (40 J/cm2 x 3 days) directed on the right posterior axillary area and a whole body exposure test (4 J/cm2 UVA, 20 mJ/cm2 UVB x 3 days) were positive both clinically and histologically on day 4.
