title: Group A streptococcal necrotizing fasciitis of the psoas muscle.
abstract: Group A streptococci are common colonizers of the skin and upper respiratory tract. Serious infections of the respiratory tract as well as the skin and soft tissue are common. Highly virulent Group A streptococci are not infrequently the cause of invasive, life-threatening infections. Necrotizing fasciitis is uncommon and rarely the result of Group A streptococci. Necrotizing fasciitis of the psoas from Group A streptococci has been reported as a complication in patients with colon cancer perforation or peritonitis. We report the first case of Group A streptococcal necrotizing fasciitis of the psoas muscle not associated with peritonitis or colon perforation.
