Rapidly recurrent prostatic obstruction due to granulomatosis with polyangiitis

Area of Science:

• Urology
• Rheumatology
• Pathology

Background:

• Granulomatous prostatitis is an uncommon condition.
• Granulomatosis with polyangiitis (GPA) is a rare systemic vasculitis.
• GPA is an infrequent cause of prostatitis.

Observation:

• A patient presented with lower urinary tract symptoms and recurrent urinary obstruction.
• The patient underwent two prostatic resections for presumed granulomatous prostatitis.
• Diagnosis of GPA was delayed, occurring after surgical interventions.

Findings:

• The case highlights granulomatous prostatitis secondary to unrecognized GPA.
• Challenges in diagnosing this rare condition are demonstrated.
• The systemic nature of GPA necessitates comprehensive patient evaluation.

Implications:

• This case underscores the importance of considering systemic diseases like GPA in unexplained prostatitis.
• Timely diagnosis of GPA can prevent unnecessary surgical procedures.
• Increased awareness among clinicians may improve patient outcomes for rare granulomatous prostatitis cases.
