Staphylococcus aureus Prostatic abscess: a clinical case report and a review of the literature

Background: Prostatic abscess is a rare complication of acute bacterial prostatitis and is most commonly caused by Enterobacteriaceae. We report on a case of prostatic abscess caused by Staphylococcus aureus and conduct a review of the literature. Case presentation: We present a case of S. aureus prostatic abscess that was successfully treated with a combination of antibiotic and surgical therapy. The isolate was non-multidrug-resistant, methicillin-resistant Staphylococcus aureus and was genotyped as clonal complex 5, an emerging regional clone that is trimethoprim resistant and Panton-Valentine leukocidin positive. This current case report is the first to describe the use of clindamycin step-down therapy. A literature review identified a further 39 cases of S. aureus prostatic abscesses, of which 26 were methicillin resistant. Conclusions: S. aureus is an uncommon cause of prostatic abscess. Optimal management includes both antibiotic therapy and surgical drainage. Our use of clindamycin as step-down therapy was guided by its excellent prostatic penetration.
