METHODS: We present the case of a 50-year-old man with multiple progressive lesions, diagnosed initially as a bacterial infection, who presented to a North American emergency department after several unsuccessful trials of antibiotic therapy. Eventually, polymerase chain reaction testing of a wound biopsy sample confirmed the presence of L. braziliensis. After a complicated course, the patient\'s infection resolved after tailored antiparasitic therapy. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case highlights the need to include travel history in the evaluation of atypical dermatologic infections.
方法:我们介绍了一个50岁的男性多发性进展性病变的病例,最初被诊断为细菌感染,在几次抗生素治疗试验失败后,他向北美急诊科就诊。最终,伤口活检样本的聚合酶链反应测试证实了巴西乳杆菌的存在。经过复杂的课程,经过量身定制的抗寄生虫治疗,患者的感染得以解决。为什么应该让紧急医生意识到这一点?:这个案例强调了在评估非典型皮肤病感染时需要包括旅行史。
