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

摘要

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.
