Hypothesis

Local recurrence of upper tract urothelial carcinoma typically occurs within 2 years post-surgery, but can it occur 10 years later as squamous cell carcinoma?

Conclusion

This case highlights the challenges in treating malignant tumors that recur as squamous cell carcinoma after a long period post-surgery.

Supporting Evidence

  • Local recurrence of upper tract urothelial carcinoma usually occurs within 2 years post-surgery.
  • This case is unique as it shows recurrence 10 years later as squamous cell carcinoma.
  • Imaging studies revealed a mass lesion in the left retroperitoneum.
  • A CT-guided biopsy confirmed the diagnosis of squamous cell carcinoma.

Takeaway

Sometimes, cancer can come back a long time after treatment, and it can look different than before, making it hard for doctors to decide what to do next.

Methodology

The case involved imaging studies and a CT-guided biopsy to diagnose the recurrence.

Limitations

The rarity of the case limits the generalizability of the findings.

Participant Demographics

67-year-old female patient.
