假膜性肠炎(肉眼)


假膜性肠炎,图示结肠黏膜表面充血,部分由黄绿色渗出物覆盖。黏膜本身并没有被侵蚀。广谱抗生素的应用(例如氯林可霉素)和/或免疫抑制剂都使得细菌例如梭状芽孢杆菌属或S. Aureus,或真菌类例如念球菌属的过度生长,引起这种表现。
This is an example of pseudomembranous enterocolitis. The mucosal surface of the colon seen here is hyperemic and is partially covered by a yellow-green exudate. The mucosa itself is not eroded. Broad spectrum antibiotic usage (such as clindamycin) and/or immunosuppression allows overgrowth of bacteria such as Clostridium dificile or S. aureus or fungi such as Candida to cause this appearance.
