Group G streptococcus leading to necrotizing soft tissue infection after left lower extremity radiofrequency venous ablation.

A 73-year-old morbidly obese woman developed a severe group G Streptococcus (GGS) necrotizing soft tissue infection (NSTI), superimposed by toxic shock-like syndrome after undergoing radiofrequency venous ablation of her left lower extremity. NSTI secondary to GGS are relatively uncommon, with only nine cases described in the literature. We present a case of GGS NSTI, a debilitating wound infection, occurring after radiofrequency venous ablation.
