title: Phototoxicity and photoallergy.
abstract: Phototoxic and photoallergic reactions resulting from a combined exposure to photosensitizing chemicals and light are common. Diagnosis of such reactions requires an understanding of its clinical presentation and recognition of commonly encountered photosensitizers. Phototesting allows identification of the photosensitizer and appropriate management of the patient.
