title: Repeated exposure to ultraviolet A in polymorphous light eruption patients and normal subjects: a clinical and histopathological study.
abstract: The clinical and histopathological responses to repeated exposures of ultraviolet A were studied in patients with polymorphous light eruption and in normal controls. Variable degrees of perivascular and diffuse infiltrates (lymphocytic and neutrophilic) were detected in both groups. These findings indicate that more specific parameters should be used to distinguish reactive from pathological responses.
