本文对1985～1995年我院皮肤科所见的糠秕孢子菌毛囊炎(PF)65例临床资料进行分析。本病的皮肤病变表现为多发的细小毛囊性血疹,其间可见散在的毛囊性小脓疱,分布在上背部、上胸部、肩部、面部、腹部及四肢。其诊断可根据典型的临床表现和皮疹的组织病理检查而决定。在组织切片中,毛囊内、毛囊壁或毛囊周围真皮内找到圆形酵母样孢子是确诊PF的有力依据。扫描电镜观察证实为圆形酵母样孢子,能看到从孢子出芽到新孢子形成的各个阶段,对该菌的孢子及菌丝的形态、大小、表面结构及芽殖作了描述。在治疗方面,用抗真菌药物治疗本病有良效。广州及澳门均处于亚热带地区、年平均温度及湿度均较高,成为两地诱发PF的重要因素。
This article from 1985 to 1995 in our hospital dermatology Pityrosporum folliculitis (PF) 65 cases of clinical data were analyzed. Skin lesions of the disease showed multiple hair follicles of small rash, during which visible scattered hair follicles small pustules, located in the upper back, upper chest, shoulders, face, abdomen and limbs. The diagnosis can be based on the typical clinical manifestations and histopathological examination of the rash decision. In histological sections, finding circular yeast-like spores in the hair follicles, follicular walls, or dermis around the hair follicles is a strong basis for the diagnosis of PF. Scanning electron microscopy confirmed the circular yeast-like spores, we can see from the spore sprouting to the formation of new spores in various stages of the spores and mycelium morphology, size, surface structure and budding were described. In the treatment, the antifungal drug treatment of the disease has good effect. Both Guangzhou and Macau are in the subtropical zone, with high annual average temperature and humidity, becoming an important factor for PF in both places.
