Multiple inverted papillomas of the urinary bladder are rare, presenting with obstructive symptoms and hematuria. Histology is key for diagnosis, with DNA-ploidy and proliferation index aiding management.

Area of Science:

  • Urology
  • Oncology
  • Pathology

Background:

  • Inverted papillomas (IPs) are rare bladder tumors.
  • Transitional cell papillomas are uncommon neoplastic lesions of the urinary bladder.

Observation:

  • A 53-year-old male presented with a year of obstructive urinary symptoms and gross hematuria.
  • Ultrasound revealed two polypoid masses in the urinary bladder.

Findings:

  • Transurethral resection and histopathological examination identified subepithelial, non-atypical cell proliferation in a trabecular pattern.
  • DNA-ploidy analysis showed a diploid population, and ki-67 staining indicated a low proliferation index.

Implications:

  • Multiple inverted papillomas of the urinary bladder are exceptionally rare.
