Write answer in between .Q:A 51-year-old man comes to the physician because of a 3-month history of diffuse perineal and scrotal pain. On a 10-point scale, he rates the pain as a 5 to 6. He reports that during this time he also has pain during ejaculation and dysuria. He did not have fever. The pain is persistent despite taking over-the-counter analgesics. He has smoked one pack of cigarettes daily for 20 years. He appears healthy and well nourished. Vital signs are within normal limits. Abdominal and scrotal examination shows no abnormalities. Rectal examination shows a mildly tender prostate without asymmetry or induration. Laboratory studies show:Hemoglobin 13.2 gdLLeukocyte count 5000mm3Platelet count 320,000mm3UrineRBC noneWBC 4-5hpfA urine culture is negative. Analysis of expressed prostatic secretions shows 6 WBCshpf N 10. Scrotal ultrasonography shows no abnormalities. Which of the following is the most likely diagnosis?? A: Prostatic abscess, B: Benign prostatic hyperplasia, C: Chronic pelvic pain syndrome, D: Chronic epididymitis, E: Bladder neck cancer,  <response>: This is a question about a 51-year-old man with a 3-month history of perineal and scrotal pain that is worse during ejaculation and urination. Important findings include no fever, normal abdominal and scrotal exam, mildly tender prostate without asymmetry or induration, normal urinalysis and urine culture, and normal scrotal ultrasound. The choices include prostatic abscess, benign prostatic hyperplasia BPH, chronic pelvic pain syndrome, chronic epididymitis, and bladder neck cancer. Prostatic abscess is unlikely given no fever, normal prostate exam, and normal urine studies. BPH would not explain the scrotal pain. Chronic epididymitis is unlikely with a normal scrotal exam and ultrasound. Bladder neck cancer is unlikely with a normal prostate exam. The diffuse nature of the pain, association with ejaculation and urination, tender prostate on exam, and lack of any other clear explanation point towards chronic pelvic pain syndrome as the most likely diagnosis.C: Chronic pelvic pain syndrome
