Lymphocele Containing Staphylococcus lugdunensis.

Area of Science:

• Microbiology
• Infectious Diseases
• Clinical Medicine

Background:

• Staphylococcus species are a major cause of bloodstream infections.
• Methicillin-resistant Staphylococcus aureus (MRSA) is associated with high mortality.
• Staphylococcus lugdunensis (S. lugdunensis) is increasingly recognized for causing severe infections.

Observation:

• A rare case of S. lugdunensis bacteremia originating from a post-surgical lymphocele is reported.
• An 80-year-old male presented with abdominal pain and fever, with S. lugdunensis identified in lymphocele fluid.
• Imaging confirmed a large lymphocele as the source of infection.

Findings:

• S. lugdunensis, a coagulase-negative staphylococci, can cause diverse infections beyond skin colonization.
• The pathogen has been linked to serious conditions like prosthetic joint infections and endocarditis.
• Despite susceptibility to many antibiotics, S. lugdunensis forms biofilms, complicating treatment.

Implications:

• This case expands the known spectrum of S. lugdunensis infections.
• Increased reporting of S. lugdunensis cases is crucial for understanding its clinical behavior and antimicrobial susceptibilities.
• Awareness of S. lugdunensis bacteremia from unusual sources like lymphoceles is important for timely diagnosis and management.
