Multiple Prostatic Abscesses Caused by Staphylococcus aureus Without Physical Findings in an Immunosuppressed Older Patient

Staphylococcus aureus is endemic to human and animal skin and the gastrointestinal tract and is highly tissue-destructive. Staphylococcus aureus bacteremia has a high mortality rate of 20%-30%. A prostatic abscess is a rare complication of acute bacterial prostatitis. The focus of S. aureus infection is elsewhere in the body, and bacteremia causes the abscess, hence difficult to diagnose. Here, we report a case of prostatic abscesses, followed by a diagnosis of S. aureus bacteremia without specific physical findings. The patient was a 72-year-old male with independent activities of daily living who developed prostate and perifemoral abscesses with multiple vague symptoms due to diabetes-related methicillin-susceptible S. aureus bacteremia. It is important to comprehensively evaluate multiple vague symptoms considering the immunological conditions of patients and investigate any suspicion of bacteremia and abscess in deep parts of the body. General physicians should be system-specific specialists to deal with multiple symptoms among older immunocompromised patients.
