Seborrheic dermatitis (SD) is a disease characterized by erythema and accompanied by greasy scale in the seborrheic region. The mechanism by which the disease occurs is still unknown. The genus Malassezia is involved in aggravating SD. Objective diagnosis of SD has yet been established. Atopic dermatitis and psoriasis or contact dermatitis are often confused with SD. One method to differentiate SD from other skin diseases is direct microscopic examination. Mild corticosteroids are effective in treatment of this condition, although, many cases recur within a few days. Antifungal agents are also effective in the treatment of SD by reducing the number of spores, which results in prolongation of the time to recurrence. It is my recommendation that antifungal agents be the first choice of therapy.
脂溢性皮炎（SD）是一种以红斑为特征且在脂溢部位伴有油腻鳞屑的疾病。该疾病的发病机制尚不清楚。马拉色菌属与加重SD有关。SD的客观诊断方法尚未确立。特应性皮炎、银屑病或接触性皮炎常与SD相混淆。将SD与其他皮肤病相鉴别的一种方法是直接显微镜检查。轻度皮质类固醇对这种情况有效，不过，许多病例在几天内就会复发。抗真菌药物通过减少孢子数量也对SD治疗有效，这会延长复发时间。我的建议是抗真菌药物应作为首选治疗方法。
