Streptococcal periorbital necrotizing fasciitis: Case series on a rare but potentially life-threatening entity.

Objective: Periorbital necrotizing soft tissue infection (NSTI) is a rare entity caused either by polymicrobial infection (type 1) or Streptococcus pyogenes and/or Staphylococcus species (type 2). A high level of clinical suspicion is necessary to make the diagnosis. We present 3 cases of NSTI illustrating our diagnostic and therapeutic approach.
