We report a case of severe Citrobacter koseri folliculitis of the face in a boy with acne. A 15-year-old boy affected by acne was admitted because of a rash located on the face. Dermatological examination revealed two large plaques, with numerous pustules, eschars and crusts, located bilaterally and symmetrically on the cheeks. Three bacteriological examinations were positive for C. koseri. The patient was successfully treated with i.m. ceftriaxone. C. koseri is a Gram-negative, aerobic, mobile, nonsporulating bacillus belonging to the Enterobacteriaceae family. It can cause meningitis, central nervous system abscess and sepsis, almost exclusively in infants and immunocompromised hosts. Respiratory tract and urinary infections have been reported in elderly people. Furthermore, rare cases of skin infections have been described.
我们报告了一例痤疮患者面部严重柠檬酸杆菌毛囊炎。一名 15 岁男孩因皮疹就诊，他患有痤疮。皮肤科检查显示双侧脸颊有两个大斑块，有大量脓疱、结痂和鳞屑。三次细菌学检查均为柠檬酸杆菌阳性。患者经肌肉注射头孢曲松成功治疗。柠檬酸杆菌是一种革兰氏阴性、需氧、移动、非孢子形成的杆菌，属于肠杆菌科。它几乎只在婴儿和免疫功能低下的宿主中引起脑膜炎、中枢神经系统脓肿和败血症。在老年人中也有呼吸道和尿路感染的报道。此外，还描述了少数皮肤感染病例。
