PNEUMOCOCCAL PYOMYOSITIS IN A PATIENT WITH HIV-INFECTION

Infections of striated muscle with abscess formation are unusual becau se muscle is relatively resistant to bacterial infections [1]. In the United States, the first cases of the syndrome known as tropical pyomy ositis were reported in 1971. Recently, Christin and Sarosi [2] review ed approximately 100 North American cases and found that Staphylococcu s aureus caused 70% of them and streptococcal species caused 16%. None of the cases was caused by Streptococcus pneumoniae. We wish to repor t a case of pyomyositis caused by S. pneumoniae in a woman with human immunodeficiency virus (HIV) infection.
