Erosive pustular dermatosis of the scalp is a rare condition that tends to occur mainly in elderly patients. Clinically it is characterized by the presence of pustules, chronic crusted erosions with progressive scarring alopecia, and skin atrophy. Although etiology remains unclear, it seems to be triggered by local trauma such as surgical procedures, skin graft, ultraviolet light exposure, cryotherapy, craniotomy, or radiotherapy. To our knowledge, erosive pustular dermatosis of the scalp after photodynamic therapy has been seldom reported. We described a 81-year-old woman presenting with erosive pustular dermatosis of the scalp after photodynamic therapy for actinic keratosis.
头皮糜烂性脓疱性皮病是一种罕见的疾病，主要发生于老年患者。临床上，其特征为出现脓疱、伴有进行性瘢痕性脱发的慢性结痂性糜烂以及皮肤萎缩。尽管病因尚不清楚，但似乎由局部创伤引发，如外科手术、皮肤移植、紫外线照射、冷冻疗法、开颅手术或放射治疗。据我们所知，光动力治疗后发生头皮糜烂性脓疱性皮病的情况鲜有报道。我们描述了一名81岁女性，在接受光动力治疗日光性角化病后出现了头皮糜烂性脓疱性皮病。
