Summary
A rare extraskeletal mesenchymal chondrosarcoma caused right ureteral obstruction in a 62-year-old patient. This intraluminal tumor required ureteronephrectomy for complete resection.
Area of Science:
- Urology
- Oncology
- Pathology
Background:
- Recurring renal colic and hematuria can indicate serious urinary tract pathology.
- Diagnostic imaging plays a crucial role in identifying the cause of urinary obstruction.
Observation:
- A 62-year-old male presented with symptoms suggestive of right kidney obstruction.
- Initial sonography and CT scans were inconclusive, necessitating retrograde ureteropyelography.
- Retrograde ureteropyelography identified a significant obstructive tumor within the right ureter.
Findings:
- Surgical resection via ureteronephrectomy revealed a 3.5 cm intraluminal extraskeletal mesenchymal chondrosarcoma.
- The tumor exhibited predominantly intraluminal growth with a tumor-free external ureteral wall.
- Histopathological examination confirmed chondrosarcoma, a site previously unreported for this tumor type.
Implications:
- This case highlights the importance of advanced imaging in diagnosing rare ureteral tumors.
- The unusual location and presentation of chondrosarcoma expand the differential diagnosis for obstructive uropathy.
- Potential pathogenetic origins include choristoma degeneration or pluripotent tumor cell development.
