Tropical pyomyositis presenting as sepsis with acute respiratory distress syndrome.

Tropical pyomyositis is an underdiagnosed condition. We reported a 35 year old male farmer, who presented with septicemia and acute respiratory distress syndrome due to pyomyositis involving the paraspinal muscles. Culture of the pus grew methicillin sensitive Staphylococcus aureus, and the patient recovered after surgical drainage and antibiotic treatment. Diagnostic delays can be avoided if tropical pyomyositis is considered as a differential diagnosis in patients with septicemia.
