Group A-streptococcal (GAS) infection can lead to various clinical presentations and is fulminant when it reaches the deep tissues, leading to a high morbidity and mortality. The severity of postpartum GAS infections is widely known. In this case report we describe the course of disease in a pregnant patient with GAS toxic shock syndrome with initial complaints of abdominal pain, diarrhea and fetal demise at first presentation. Within 10 hours this patient died. It is important to stay vigilant for a fulminant GAS infection in pregnant patients, to recognize it quickly and treat it adequately.
