Background
- Primary bacterial infection of skeletal muscles
- Also known as myositis tropicans, more common in tropical settings
- Temperate climates in immune compromised patients
Clinical Features
- First stage: localized muscle pain, low grade fevers, vague complaints[1]
- Localized muscle inflammation without abscess
- Second stage: Worsening pain, muscle swelling, fever, abscess formation
- Third stage: Infection dissemination, septic shock
Pathophysiology
- Transient bacteremia after minor trauma to muscle group, or vigorous exercise[2]
- Most commonly Staphylococcus Aureus, followed by Strep pyogenes, pneumococcus,neisseria, haemophilus, ]]yersinia]], pseudomonas, klebsiella, and escherichia
Risk Factors
- DM
- HIV
- IVDU
- Renal failure
- Rheumatoid Arthritis
