Summary
Solitary fibrous tumors (SFTs) are rare renal neoplasms. This case highlights the unpredictable behavior of malignant renal SFT, showing local recurrence one year after surgery despite initial negative imaging.
Area of Science:
- Oncology
- Pathology
- Urology
Background:
- Solitary fibrous tumors (SFTs) are rare mesenchymal neoplasms, typically originating in the pleura.
- Renal SFTs are exceptionally uncommon, with limited data on their behavior post-resection.
- Local recurrence following complete surgical removal of renal SFT is infrequently documented.
