Gas gangrene of the head and neck is a very rare condition, and non-clostridial gas-forming neck abscess caused by Klebsiella pneumoniae is unusual. This report is of a diabetic man with poor dental hygiene, a right dental abscess, and parapharyngeal abscess with gas gangrene due to Klebsiella pneumoniae infection, presenting with septic shock and multiorgan failure, who recovered after surgical neck debridement.
