Contact allergic sensitivity to plants and the photosensitivity dermatitis and actinic reticuloid syndrome

Abstract

Contact allergic sensitivity to oleoresin extracts from Compositae plants was found to be usually present in individuals suffering from the photosensitivity dermatitis and actinic reticuloid syndrome. It was demonstrated in forty-seven out of fifty-five examples of this syndrome. These results provide support for the view that contact allergic sensitivity is an important aspect of the state of chronic photosensitivity in the middle-aged and elderly male.
