Granulomatous prostatitis induced by capsule-deficient cryptococcal infection.

A 59-year-old man with prostatism, in otherwise good health, was treated with transurethral prostatectomy and ketoconazole. At microscopic examination of the prostatic tissue he had acute and chronic prostatitis with granulomatous lesions, in the center of which capsular-deficient cryptococcal organisms were demonstrated. The patient was well without evidence of systemic or local infection at 22 months. The differential diagnosis of granulomatous prostatitis is discussed.
