Streptococcal necrotizing fasciitis with toxic shock syndrome following cervical adenitis.

In the recent years an increase of serious invasive infections due to Group A Streptococcus have been reported. Necrotizing fasciitis is a rapidly progressive soft tissue infection characterized by necrosis of the subcutaneous tissues and superficial fascia. We report a case of necrotizing fasciitis and toxic shock syndrome following cervical adenitis in a previously healthy 11-month-old boy. Cultures from blood and the necrotic lymph node grew Group A Streptococcus. Group A Streptococcus belonging to M1 serotype and producing streptococcal pyrogenic exotoxin, SPE A was identified. Full recovery was achieved by aggressive treatment, which included intensive care support, extensive surgical debridement of necrotic lesions and antibiotic treatment with the combination of penicillin and clindamycin.
