Folliculitis decalvans (FD) is a chronic inflammatory disease with an unknown etiology. FD is characterized by chronic suppurative folliculitis, is often accompanied by pruritus or even pain, and ultimately progresses to cicatricial alopecia. Adult men have a tendency to develop this disease. The current treatments mainly consist of antibiotics, vitamin A derivatives, immune therapies, and biologics. However, some cases are intractable. Here, we present a case of recalcitrant FD that was successfully treated by photodynamic therapy with topical aminolevulinic acid.
脱发性毛囊炎（FD）是一种病因不明的慢性炎症性疾病。FD的特征为慢性化脓性毛囊炎，常伴有瘙痒甚至疼痛，最终发展为瘢痕性脱发。成年男性有患此病的倾向。目前的治疗方法主要包括抗生素、维生素A衍生物、免疫疗法和生物制剂。然而，有些病例难以治疗。在此，我们报告一例顽固性FD患者，通过外用氨基乙酰丙酸光动力疗法成功治愈。
