摘　　要：目的探讨星座链球菌致面部脓肿的诊断学特征。方法回顾性分析2020年6月27日天门市第一人民医院肿瘤科收治的1例星座链球菌致面部脓肿患者的临床资料,并文献复习。结果患者临床表现为右颌面部肿块,肿块部分皮肤破溃,且有脓性分泌物流出;既往有鼻咽癌病史。影像学提示右侧中耳乳突炎、鼻窦炎;实验室检查:人类疱疹病毒IgA抗体为弱阳性,C-反应蛋白11.07 mg/L,降钙素原1.26μg/L。血培养阴性,伤口分泌物检出星座链球菌,对红霉素、克林霉素耐药。结论星座链球菌作为一种机会致病菌,可引起人体各组织器官发生化脓性感染,应引起临床重视并提高病原菌的检出率,做到早诊断、早治疗。Objective To investigate the diagnostic characteristics of facial abscess caused by Streptococcus constellatus.Methods The clinical data of a case of facial abscess caused by Streptococcus constellatus admitted to the Oncology Department of Tianmen First People′s Hospital on June 27,2020 were retrospectively analyzed,and the relevant literatures were reviewed.Results The patient presented with a mass in the right maxillofacial region,with partial skin ulceration and purulent discharge.The patient had an anamnesis of nasopharyngeal carcinoma.Imaging indicated right middle ear mastoiditis and sinusitis.Laboratory examination found that IgA antibody of human herpesvirus was weakly positive,C-reactive protein level was 11.07 mg/L,procalcitonin level was 1.26μg/L,blood culture was negative,and Streptococcus constellatus was detected in wound secretion.The pathogen was resistant to erythromycin and clindamycin.Conclusion s As a kind of opportunistic pathogen,Streptococcus constellatus can cause suppurative infection in various tissues and organs of human body,which should arouse clinical attention.We should improve the detection rate of pathogenic bacteria,so as to achieve early diagnosis and treatment.
