Summary

Transitional cell carcinoma was found in an ectopic upper pole ureter within a duplicated collecting system in an 81-year-old male. This case highlights rare urinary tract anomalies and associated cancer risks.

Area of Science:

  • Urology
  • Oncology
  • Medical Case Reports

Background:

  • Urinary tract duplication is a congenital anomaly with varied presentations.
  • Transitional cell carcinoma (TCC) typically arises in the bladder or renal pelvis.
  • Ectopic ureters can predispose to urinary stasis and infection, but malignancy is rare.

Observation:

  • An 81-year-old male presented with symptoms related to a urinary tract abnormality.
  • Imaging revealed a completely duplicated collecting system with an ectopically located upper pole ureter.
  • A transitional cell carcinoma was identified within this ectopic ureter.

Findings:

  • The coexistence of a duplicated collecting system, ectopic ureter, and TCC is exceptionally rare.
  • The tumor's location within the ectopic ureter presented unique diagnostic and management challenges.
  • Histopathological confirmation of transitional cell carcinoma was established.

Implications:

  • This case underscores the importance of thorough evaluation in patients with congenital urinary tract anomalies.
  • It expands the understanding of rare tumor locations within the urinary system.
  • Management strategies for TCC in ectopic ureters may require tailored approaches.
