[Cervical necrotizing fasciitis disclosing HIV infection].

Necrotizing fasciitis is a rapidly progressing necrotizing process which affects subcutaneous tissue and fascia. The leading cause of these infections in neck is odontogenic infection. Its occurrence is reported to be rare, but often fatal. The therapeutic regimen includes three essential principles: appropriate antimicrobial therapy, prompt surgical treatment, and supportive measures. Two cases of cervical necrotizing fasciitis revealing human immunodeficiency virus (HIV) infection are reported. Clinicians should be aware of this underlying condition, and every patient with cervical necrotizing fasciitis should be tested for HIV.
