Cervical necrotizing fasciitis is a fulminant infection that spreads along the fascial planes, causing subcutaneous tissue death characterized by rapid progression and systemic toxicity. Dental infection is the most common nidus of cervical necrotizing fasciitis. Strep-tococcus and Staphylococcus species are found to be the most commonly isolated organisms in many bacteriological analyses of cervical necrotizing fasciitis. We describe a case of a 29-year-old female who was diagnosed with acute suppurative parotitis first. After admission, her illness progressed to cervical necrotizing fasciitis. She underwent surgery of incision and drainage, and pus culture yielded Klebsiella pneumoniae (K. pneumoniae). To the best of our knowledge, cervi-cal necrotizing fasciitis is seldom secondary to bacterial parotitis, and rarely caused by K. pneumoniae.
