Ecthyma gangrenosum (EG) involving the external ear canal is an unusual presentation.
To describe a case of EG diagnosed in a 5-day-old female who was admitted to our institute with multiple soft-tissue lesions involving the right arm, forearm, back, and perineum and with a complete facial palsy associated with ipsilateral external otitis.
The patient presented neonatal sepsis associated with significant leucopenia, thrombocytopenia and alteration of the coagulation profile. Microbiological analysis was performed on the purulent otorrhea and on the exudate material collected at the level of the genital lesion; both of these specimens tested positive for the presence of Pseudomonas aeruginosa. An intravenous antibiotic treatment was administered and a rapid improvement from the infection was observed.
The rare occurrence of this presentation, combined with the potential for fatal complications from EG if not swiftly diagnosed underline the importance of this case.
坏疽性脓皮病累及外耳道是一种不寻常的表现。
描述一例5日龄女性坏疽性脓皮病的病例，该患儿因右臂、前臂、背部和会阴多处软组织病变以及与同侧外耳道炎相关的完全性面瘫入住我院。
该患者出现新生儿败血症，伴有明显的白细胞减少、血小板减少和凝血指标改变。对脓性耳漏和生殖器病变部位采集的渗出物进行了微生物分析；这两个标本均检测出铜绿假单胞菌阳性。给予静脉抗生素治疗，感染情况迅速改善。
这种表现的罕见性，以及坏疽性脓皮病若不迅速诊断可能导致致命并发症，突显了该病例的重要性。
