The lesions were mainly distributed on the exposed areas. （2）Photo-sensitive tests of 93 patients showed that the average value of UVA-MPPDwas 7.39 JPcm2 and that of UVB-MED was 20.91 mJPcm2. （3）The results of photo-patch test in 83 patients showed that 48 patients （67.8%）had positive reactions in patch test， and the most common contactant was balsam peru. Fifty-eight patients（69.9%）had positive reactions in photo-patch test indicating that the most common contactant in photo-patch test was balsam peru．Conclusions CAD appears mostly in the middle aged and the aged males and the lesions are mainly distributed on exposed areas.
