[Primary pyomyositis in mild climates. Presentation of 2 new cases]

Pyomyositis is an acute bacterial infection which affects striated muscles. It is a relatively rare process in mild climates. Staphylococcus aureus is responsible for 90-95% of cases. Klebsiella pneumoniae pyomyositis is extremely rare with only one other case reported in a mild climate. Two new cases of pyomyositis are described one caused by K. pneumoniae, increasing thus the etiology spectrum in our country, and the other caused by S. aureus ending in fatality, with two focus of pyomyositis (one of which was chronic) and multisystemic secondary affectation. We highlight the appearance of this process in our environment and the necessity to keep it in mind when making a differential diagnosis in order to recognize it and treat it as soon as possible since its prognosis depends on the moment the diagnosis is made.
