Abstract：
Dissecting cellulitis of the scalp (DCS) is a rare skin disease and understudied. The aim of the study was to collect the demographic, clinical features and laboratory tests of patients with DCS in a dermatology outpatient clinic. A cross-sectional study was conducted in a department of dermatology in Beijing. Patients whose diagnoses have included DCS were selected from July 2021 to December 2021. DCS patients were stratified according to whether they were follicular occlusion triad (FOT) or not. There were 169 patients with DCS included. All 169 patients were male, and the median patient age was 32 years. The most common comorbidities in this study were seborrheic dermatitis (10.65%). Over 1/3 of patients had elevated white blood cell (WBC) and neutrophil counts, and 12 of 18 patients had dyslipidemia. CD8+ T cell counts increased in 15 of 26 patients while CD4+ T/CD8+ T ratios were all normal. DCS mainly affects men in their thirties. More research about DCS is needed to clarify the clinical significance of laboratory tests.
摘要：
解剖头皮蜂窝织炎（DCS）是一种罕见的皮肤病，研究不足。这项研究的目的是收集人口统计，皮肤科门诊DCS患者的临床特征和实验室检查。在北京皮肤科进行了一项横断面研究。从2021年7月至2021年12月选择诊断包括DCS的患者。根据是否为卵泡闭塞三联征（FOT）对DCS患者进行分层。纳入DCS患者169例。169例患者均为男性,患者年龄中位数为32岁.本研究中最常见的合并症是脂溢性皮炎(10.65%)。超过1/3的患者白细胞（WBC）和中性粒细胞计数升高，18例患者中有12例患有血脂异常。26例患者中有15例CD8T细胞计数增加，而CD4T/CD8T比值均正常。DCS主要影响30多岁的男性。需要更多关于DCS的研究来阐明实验室检查的临床意义。
