BACKGROUND: Polymorphous light @entity203 (PLE) is an idiopathic @entity203 induced by ultraviolet (UV) radiation (UVR). OBJECTIVE: Evaluation of the clinical aspects, diagnostic criteria of PLE in a major Swiss referral center. METHODS: 25 @entity1 with PLE were tested with a standardized protocol for the assessment of photodermatoses. RESULTS: 25 @entity1 (22 @entity1 vs. 3 @entity1 ) were identified. Papular and papular-vesicular eruptions were the most common clinical presentations. 6 of 25 @entity1 had a reduced minimal erythema dose (MED) for UVA and 8 of 25 @entity1 had a reduced MED for UVB. Photoprovocation was positive in 11 of 20 @entity1 for UVA and 7 of 20 @entity1 for UVB. Photohardening with @entity543 was successful in 8 of 10 @entity1 . Combined UVA/UVB therapy had a satisfactory effect in 10 of 15 @entity1 . Narrow-band UVB therapy was still successful after ineffective UVA/UVB therapy. CONCLUSION: The MED was of no value for the diagnosis of PLE. The typical lesions were reproduced by UVA and UVB photoprovocation. We recommend photohardening with @entity543 (311 nm).
