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. Age, gender, skin type, family history and presence of atopy were considered. UVA and UVB MEDs and provocative phototests with UVA and UVB were obtained with a standardized procedure. Photopatch tests were applied according to the IRCDG rules. ANA were assessed by indirect immunofluorescence.

Results: Four criteria (predominance of women, shorter latency, uninvolvement of the face and absence of relapse during summer) identified BSLE in only 6.1% of cases. All had positive phototests, mostly with UVA. Uninvolvement of face, short latency and no seasonal relapses identified 11.7% patients, mostly with positive phototests to UVA. Short latency and no seasonal relapses in women identified 11.2% patients. Uninvolvement of face and no seasonal relapses in women identified 8.1% of patients. Uninvolvement of face and short latency in women identified 17.6% of patients.

Conclusion: Criteria diagnosed BSLE in only a minority of patients, who were positive at phototesting, mostly with UVA.

[Does benign summer light eruption exist?].

Ann Dermatol Venereol 2002 Jun-Jul;129(6-7):855-8

Service de Dermatologie, CHU de Caen, Cedex, France.

Background: Contrary to other countries, in which a unique entity is recognized, two sub-groups of light eruption, benign summer light eruption and polymorphous light eruption, are identified in France. Benign summer light eruption was individualized with a few criteria: age at onset between 25-35 years old, female predominance, onset within 12 hours after an intensive exposure to sun, presence of lesions on areas which have not been regularly exposed to sunlight such as the upper chest, absence of lesions on the face, improvement during the summer period and negativity of the polychromatic phototest. In fact patients usually presenting with benign summer light eruption do not have all the criteria and they gradually develop a polymorphous light eruption. Read More

Experimental reproduction of polymorphous light eruption and benign summer light eruption by whole-body UVA irradiation.

Dermatology 1997 ;194(4):388-91

Department of Dermatology, University Hospital of Antwerp, Belgium.

The entity 'benign summer light eruption' (BSLE) has been introduced to make a clinical subdivision in the heterogeneous group of polymorphous light eruptions (PLE). Provocation tests for PLE are not always easy to perform and require expensive apparatus. Our purpose was to evaluate a provocation test that could be readily done by a dermatologist with a UVA cabin. Read More

Polymorphous light eruption.

J Eur Acad Dermatol Venereol 2002 May;16(3):193-206

Department of Dermatology, University of Athens School of Medicine, Andreas Sygros Hospital for Skin and Venereal Diseases, 5 Dragoumi Street, Kesariani 161 21, Athens, Greece.

Polymorphous light eruption (PLE) is a common idiopathic photosensitivity disorder with an estimated prevalence of 10-20%. It is characterized by an intermittent skin reaction to ultraviolet (UV) radiation exposure, consisting of non-scarring pruritic erythematous papules, vesicles or plaques that develop on light-exposed skin. Despite the different morphology in different individuals, the eruption tends to have a monomorphous presentation in any single subject. Read More

Lupus-like phototriggering in a young woman with benign summer light eruption.

Photodermatol Photoimmunol Photomed 2005 Feb;21(1):53-5

Department of Dermatology, Purpan Hospital, TSA 40031, 31059 Toulouse cedex 9, France.

We report the case of a young woman with a single history of benign summer light eruption (BSLE) who developed delayed onset annular lupus-like lesions triggered by a polychromatic phototest, 6 weeks after the irradiation. BSLE of French authors is an idiopathic photodermatosis that corresponds to the minor form of polymorphic light eruption (PLE) of Anglo-Saxon authors. This patient may develop a true lupus erythematosus in the future as indicated by this lupus-like phototriggering and in view of the high prevalence of PLE in lupus patients. Read More
