title: Chronic actinic dermatitis: a retrospective analysis of 44 cases referred to an Australian photobiology clinic.
abstract: A retrospective study was performed to analyse the clinical and photobiological features and therapeutic outcomes of 44 patients with chronic actinic dermatitis who were evaluated over an 8.3-year period. The study population comprised 37 men and seven women with a mean age of 62.7 years (range 26-85 years). The most common abnormal phototest results were decreased minimal erythema doses to both UVA and -B (73.8%), and to UVA alone (14.3%). Twenty-six patients (78.8%) had at least one allergic, photoallergic or combined allergic/photoallergic reaction. A total of 139 positive contact or photocontact reactions were recorded (mean 4.2 per patient). Most commonly, treatment consisted of photoprotection, topical corticosteroids and episodic use of systemic agents, in particular azathioprine.
