[Group A Streptococcus pyomyositis].
BACKGROUND
Pyomyositis is a group of infectious diseases involving muscle tissue. Staphylococcus aureus is usually the causal agent. Group A Streptococcus infections are uncommonly isolated in pyomyositis. Streptococcal pyomyositis can be distinguished by its severity. Death rate may be as high as 50%.


METHODS
Diagnosis of cervical pyomyositis was made in 2 patients on the basis of ultrasound and computerized tomography findings. Group A Streptococcus was isolated from local samples. The diagnosis was confirmed at surgery. Host defense mechanisms were not deficient in either patient. Outcome was favorable in both patients after antibiotic therapy.


CONCLUSIONS
Because of the seventy of group A streptococcal pyomyositis, early diagnosis is essential for prognosis. Ultrasound and computerized tomography are very helpful. Group A streptococcal pyomyositis should be considered as a life-threatening disease.
