[Psoas abscess caused by Staphylococcus lugdunensis]

Abstract

Staphylococcus lugdunensis is a coagulase-negative staphylococcus of growing importance and atypical behavior. The infections caused by this microorganism are becoming more frequent, having a broader spectrum. Psoas abscesses caused by this germ are rare, with few cases reported in the literature. In this work, we present a case of a psoas abscess caused by S. lugdunensis in a patient suffering from diabetes mellitus and rheumatoid arthritis, which was treated with intravenous cloxacillin with a good outcome.
