乾癬病患出現光敏感現象要考慮併發光敏感疾病的可能性,我們報告一個乾癬合併系統性紅斑性狼瘡及亞急性皮膚紅斑性狼瘡的罕見病例。一27歲女性在上背部出現數個環形的板塊約一個月,其他皮膚表現還包括了頭皮上一紅色具有脫屑性的板塊。病患原即有乾癬病史八年。根據美國免疫風濕學院修正後的分類標準,病患同時符合了系統性紅斑性狼瘡的診斷。我們也回顧了有關乾癬合併紅斑性狼瘡在治療上的文獻記載。
Photosensitive disorders should be considered in patients with psoriasis who have photosensitivity. We reported a rare case of psoriasis combined with systemic lupus erythematosus and subacute cutaneous lupus erythematosus. A 27-year-old female presented with several annular plaques on the upper back for one month. Other dermatologic findings revealed erythematous plaques with mild scaling on the scalp. The patient also already has had psoriasis for 8 years. According to the American College of Rheumatology’s revised criteria, the patient met the diagnosis of systemic lupus erythematosus. We have also reviewed the literature about the treatment for psoriasis combined with lupus erythematosus.
