RESUMEN
Abstract Staphylococcus lugdunensis is a rare virulent coagulase-negative staphylococcus (CoNS) that behaves similarly to Staphylococcus aureus in causing deep abscesses, skin and soft tissue infections, and central nervous system infections. Additionally, there can be certain blood stream infections including sepsis, septic shock, toxic shock syndrome, and endocarditis complicated by embolic events. Reports of septic arthritis of a native joint associated with this organism have been infrequent, justifying the presentation and discussion of this case.

Abstract: Vancomycin is the first-line agent for the treatment of bacteremia, endocarditis, pneumonia, cellulitis, and osteomyelitis. Pancytopenia is an uncommon adverse effect of vancomycin therapy, with only a few cases of vancomycin-related neutropenia and pancytopenia described in the literature. We describe a case of a 56-year-old man who was diagnosed with chronic paraspinal abscess and started on intravenous vancomycin. He was re-admitted two weeks later with new-onset pancytopenia. Discontinuation of vancomycin resulted in improved cell counts. Physicians should monitor cell counts in patients who are on long-term intravenous vancomycin.
