A 6-year-old boy with bloody diarrhea was diagnosed with group A beta-hemolytic streptococcal hemorrhagic colitis. Complications included pharyngitis and impetigo, both caused by the same organisms. In addition to being isolated from stools, Streptococcus pyogenes was also isolated from skin lesions. Furthermore, a rapid group A streptococcal antigen test by throat swab was also positive. Hemorrhagic colitis caused by group A beta-hemolytic streptococcus is extremely rare, and much rarer are its complications with pharyngitis and impetigo. Compared with findings in reports of group A beta-hemolytic streptococcal proctitis and perianal and perineal diseases, this case suggests a distinct pathogenesis for hemorrhagic colitis.
一名6岁血性腹泻男孩被诊断为A组β溶血性链球菌出血性结肠炎。并发症包括咽炎和脓疱病，均由相同病原体引起。除了从粪便中分离出化脓性链球菌外，还从皮肤病变处分离出该菌。此外，通过咽拭子进行的A组链球菌快速抗原检测也呈阳性。A组β溶血性链球菌引起的出血性结肠炎极为罕见，其并发咽炎和脓疱病的情况则更为罕见。与A组β溶血性链球菌直肠炎及肛周和会阴疾病的报告结果相比，该病例提示出血性结肠炎有独特的发病机制。
