Abstract:

Puerperal infection is a common infectious disease in obstetrics. β-hemolytic streptococcus, Escherichia coli, and Staphylococcus aureus are the main causative microorganisms of puerperal infection, and Corynebacterium is very rare cause of puerperal infections. There are many types of puerperal infections, such as acute cervicitis, endometritis, uterine myositis, acute pelvic connective tissue inflammation, acute salpingitis, and acute pelvic peritonitis, etc. Vaginitis, cervicitis, and endometritis are relatively common, and uterine myositis is less common. We report a case of uterine myositis caused by Corynebacterium infection after spontaneous delivery, which was treated with antibiotics but the infection was not controlled and resulted in hysterectomy. The purpose of this case is to raise clinicians′ awareness of the importance of puerperal infection caused by Corynebacterium. Once infection occurs, it rapidly causes uterine myositis and the formation of a large intrauterine mass, which should be surgically removed as soon as possible.
