Psoriasis is a chronic, recurrent, and relatively common inflammatory dermatologic condition, which demonstrates various clinical manifestations including hair loss. It was once believed that alopecia was not a presentation of scalp psoriasis, but it is now widely accepted that psoriatic alopecia exists. Although the majority of patients get hair regrowth, it can potentially lead to permanent hair loss. Herein, we report a case of 26-year-old female patient with systemic lupus erythematosus who presented with scalp hair loss and nonpruritic scaly plaques on the scalp. Her clinical presentation, dermoscopic, and histopathologic findings were consistent with psoriatic alopecia. Additionally, we also described a novel scalp dermoscopic pattern of "patchy dotted vessels" which we detected in the lesion of scalp psoriasis.
银屑病是一种慢性、复发性且相对常见的炎症性皮肤病，具有包括脱发在内的多种临床表现。曾一度认为脱发不是头皮银屑病的表现，但现在银屑病性脱发已被广泛认可。尽管大多数患者的头发会再生，但也可能导致永久性脱发。在此，我们报告一例26岁患有系统性红斑狼疮的女性患者，其出现头皮脱发以及头皮上无瘙痒的鳞屑斑块。她的临床表现、皮肤镜检查和组织病理学结果均符合银屑病性脱发。此外，我们还描述了一种在头皮银屑病皮损中检测到的新型头皮皮肤镜模式——“斑片状点状血管”。
