Summary

A rare prostatic cystadenoma causing urinary retention was identified in a 45-year-old man. Surgical removal revealed a large, multilocular tumor confirmed by microscopic and immunohistochemical analysis.

Area of Science:

  • Urology
  • Pathology
  • Oncology

Background:

  • Prostatic cystadenoma is a rare benign tumor.
  • Urinary retention can be a symptom of prostatic abnormalities.

Observation:

  • A 45-year-old male presented with urinary retention.
  • Rectal examination revealed a large prostatic mass.
  • CT scan showed a multilocular tumor in the left prostate lobe.

Findings:

  • Slightly elevated prostatic acid phosphatase (PAP) and prostate-specific antigen (PSA) levels were noted.
  • A 210g multilocular tumor was surgically enucleated.
  • Microscopic examination showed epithelial-lined cysts with papillary projections.
  • Immunohistochemistry confirmed epithelial cell reactivity for PAP and PSA.

Implications:

  • This case highlights prostatic cystadenoma as a differential diagnosis for urinary retention.
  • Understanding the pathological and immunohistochemical features is crucial for diagnosis.
  • Further research may elucidate the specific origins and behavior of prostatic cystadenomas.
