Atypical Presentation of Klebsiella pneumoniae Necrotizing Fasciitis of the Lower Extremities: Silent but Deadly: A Case Report.

CASE: There has been an emerging trend of Klebsiella pneumoniae necrotizing fasciitis (KP-NF). We report a 50-year-old Chinese woman with rapidly progressive KP-NF, presenting atypically with innocuous skin symptoms. She had newly diagnosed diabetes mellitus. She had extensive subcutaneous crepitus in her lower limbs with subcutaneous gas on x-rays. Despite aggressive surgical debridement, she succumbed to septic shock and multiorgan failure. CONCLUSION: KP-NF is an emerging clinical entity and is associated with a compromised host immunity and high mortality rates. Clinicians must be aware that not all may present with the typical fulminant features and should maintain a high index of suspicion.
