Bilateral Necrotizing Fasciitis of the Foot Associated with Group B Streptococcus.

Necrotizing fasciitis (NF) is a severe bacterial infection involving fascia and subcutaneous tissue. It generally affects upper or lower extremities unilaterally, and there are few reports of bilateral-extremity NF. Here, we report a case of a 43-year-old male with type 1 diabetes who had NF on the left foot and subsequently developed NF on the other foot 1 week later.
