Abstract
Streptococcal toxic-shock syndrome is a severe infection that can cause sudden and rapid progression to septic shock and multiple organ failure. It can even affect patients without any underlying conditions. Therefore, a prompt diagnosis and treatment of this condition are essential. However, as the condition progresses on an hourly basis, the mortality rate increases. We herein report a case of streptococcal toxic-shock syndrome accompanied by a left iliopsoas abscess. Emergency surgical drainage successfully resolved the infection, thereby saving the patient’s life. We report this case along with a review of the relevant literature.

(a) A skin incision was made along the iliac crest posterior to the superior anterior iliac spine to preserve the lateral femoral cutaneous nerve. (b) The iliacus muscle was accessed through blunt dissection, revealing partially necrotic tissue and dark-red exudate. After removing the necrotic muscle, the area was irrigated with 2 liters of saline. (c) A vacuum drain was placed at the area and the wound was closed.
