Summary
A retroperitoneal leiomyosarcoma caused left kidney hydronephrosis and flank pain. Early surgical removal is crucial, even with potential recurrence, as demonstrated in this case report.
Area of Science:
- Urology
- Oncology
- Pathology
Background:
- Retroperitoneal tumors are rare and can present with vague symptoms.
- Leiomyosarcoma is a malignant mesenchymal tumor that can arise in various locations.
Observation:
- A 76-year-old woman presented with left flank pain and non-functioning left kidney.
- Imaging revealed left kidney hydronephrosis and a ureteral mass.
- Diagnostic workup included excretory urography, retrograde pyelography, ultrasonography, CT, and MRI.
Findings:
- Surgical resection of the tumor, upper ureter, and kidney was performed.
- The resected tumor measured 5 x 3 x 2.5 cm.
- Pathological diagnosis confirmed retroperitoneal leiomyosarcoma.
Implications:
- Recurrent pelvic tumor observed 14 months post-operation.
- Patient maintained good general condition with no other recurrent disease.
- Highlights the importance of early surgical intervention for retroperitoneal leiomyosarcomas.
