We report a 59-year-old man with photosensitive and photodistributed pityriasis rubra pilaris. The phototriggering of the lesions was obtained by the iterative polychromatic phototest (3 times the minimal erythema dose (MED) on 3 consecutive days) and was also observed on the supra MED sites, which began the 10th day and persisted several months. Our results are comparable to those already obtained in photosensitive psoriasis, which helped us to identify the clinical similarities of photosensitivity in these two instances of dermatosis.
我们报告了一名59岁的男性，患有光敏性和光分布性毛发红糠疹。通过反复多色光试验（连续3天给予3倍最小红斑量（MED））诱发皮损，且在超过MED的部位也观察到了这种情况，这些部位在第10天开始出现并持续了数月。我们的结果与光敏性银屑病已获得的结果相当，这有助于我们识别这两种皮肤病光敏性方面的临床相似性。
