[A report of two cases of cervical necrotizing soft-tissue infection].

Two recent cases of cervical necrotizing soft-tissue infection are herein presented. Case 1. A 52-year-old man with uncontrolled diabetes was hospitalized because of an erythematous swelling of the left side of his neck and high grade fever. Fetid yellowish pus exuded from the left parotid area. The swelling extended from the left temporal area to the left supraclavicular fossa, with necrosis of the parotid gland, sternocleidomastoid, masseter and a portion of the strap muscles. Wound cultures revealed Staphylococcus aureus and alpha-hemolytic streptococcus. No anaerobic bacteria were detected. Treatment consisted of intravenous administration of antibiotics, control of diabetes with insulin, and debridement of the necrotic tissue, which left an epidermal defect in the initially swollen area. Transfer of a forearm free flap was done after the growth of healthy granulation tissue over the affected area. Case 2. A 55-year-old woman with rheumatoid arthritis was transferred to our hospital after tracheotomy performed in another hospital because of dyspnea due to severe crepitant swelling of her cheeks and submandibular areas bilaterally, and her left temporal area. A copious amount of fetid pus exuded from the incisions made in the left temporal area, left cheek, and right submandibular area. There were bilateral diffuse rales. Culturing the pus revealed alpha-hemolytic streptococci, while MRSA and Pseudomonas aeruginosa were detected from cultures of sputum. No anaerobic bacteria were found. After intravenous administration of antibiotics, infected wounds and pneumonia were ameliorated, and necrotic subcutaneous tissue and fascia were debrided. The patient was discharged with a residual depression in her left cheek and a scar on her left temporal area.
