This study reports a rare case of benign prostatic tissue found outside the urinary tract. Ectopic prostatic tissue can mimic other conditions, highlighting the importance of accurate histologic diagnosis.

Area of Science:

  • Urology
  • Pathology
  • Anatomical Variations

Background:

  • Ectopic prostatic tissue, defined as benign prostatic tissue located outside the normal prostate gland boundaries, is an uncommon condition.
  • Preoperative diagnosis can be challenging, often requiring advanced imaging and differential diagnosis considerations.

Observation:

  • A 64-year-old male presented with a 4-month history of dysuria and urinary frequency.
  • A mass was identified posterior to the bladder on imaging.
  • Initial preoperative diagnosis suggested a left seminal vesicle tumor.

Findings:

  • Histologic examination confirmed the mass to be benign prostatic tissue.
  • This represents the seventh documented case of ectopic prostatic tissue outside the urinary tract.

  • The case underscores the diverse presentations of prostatic anomalies.

    • Implications:

    • Accurate histologic examination is crucial for diagnosing ectopic prostatic tissue.
    • Understanding rare anatomical variations is important for surgical planning and patient management.
    • This case contributes to the limited literature on ectopic prostatic tissue, aiding future research and clinical awareness.
