耳廓苏黎世放线菌病首例报告及文献复习

本文对某院收治的一例放线菌化脓性耳廓软膜炎的诊治进行了回顾性分析。患者因右耳廓急性红肿、疼痛2 d入院，入院当天即行耳廓脓肿切开引流，脓液送细菌培养。4 d后脓液培养结果回报为苏黎世放线菌，诊断为右耳廓苏黎世放线菌病。随后相继使用大剂量青霉素G静脉滴注、阿莫西林口服，共治疗3个半月，耳廓红肿消退、未变形或遗留瘢痕，停药后继续随访3个月无复发。提示苏黎世放线菌感染需早诊断，大剂量、足疗程的抗菌药物治疗，脓肿形成时及时切开引流，可避免因漏诊而未得到及时治疗导致的外耳廓瘢痕、畸形以及功能的损伤。

Actinomycosis caused by Actinomyces turicensis: the first case report and literature review

A retrospective analysis on one case of purulent perichondritis of auricle caused by Actinomyces was performed. Patient was admitted to a hospital due to acute swelling and pain in right auricle for 2 days, on the day of admission, patient underwent incision and drainage of auricle abscess, pus was performed bacterial culture. Pus culture result after 4 days was Actinomyces turicensis, actinomycosis of right auricle was diagnosed. Patient was given large dose of penicillin G intravenously drip, then oral administration of amoxicillin, treatment lasted three and a half months, auricular redness and swelling subsided, there was no deformation or residual scar, follow-up for 3 months after withdrawal of drugs showed no recurrence. It is suggested that the infection caused by Actinomyces turicensis should be diagnosed early, treated with antimicrobial agents of high dose and enough therapy course, timely incision and drainage during abscess formation can avoid scar, deformity and functional damage of external auricle caused by missed diagnosis and untimely treatment.
