Summary
Solitary fibrous tumours (SFTs) are rare neoplasms found in diverse locations. This study presents two new cases and reviews literature on SFTs, highlighting diagnostic challenges and clinical behavior.
Area of Science:
- Pathology
- Oncology
Background:
- Solitary fibrous tumours (SFTs) were initially described in the pleura but are now recognized in numerous anatomical sites.
- The rarity of SFTs hinders a complete understanding of their histogenesis, clinical behavior, treatment, and prognosis.
Observation:
- Two novel cases of SFTs are presented: one causing obstructive uropathy and incidentally discovered during renal trauma evaluation, and another located in the spermatic cord.
- These cases illustrate the varied clinical presentations and anatomical locations of SFTs.
Findings:
- SFTs can manifest in virtually all anatomical sites, posing diagnostic challenges, particularly in extra-thoracic locations.
- Accurate differential diagnosis is crucial to distinguish SFTs from more aggressive mesenchymal tumours.
Implications:
- The findings underscore the importance of considering SFTs in the differential diagnosis of masses in various anatomical locations.
- Further research is needed to elucidate the biology, clinical management, and prognostic factors of solitary fibrous tumours.
