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.
