Key result
Radical nephrectomy achieves 15-month disease-free survival in a primary undifferentiated renal liposarcoma case.
Why the study?
Liposarcomas rarely occur as a single lesion in the kidney, prompting a review of treatment options and prognostic factors for survival.
Case Report (n=1)
This case report highlights the rare presentation of primary undifferentiated liposarcoma of the kidney and its successful initial management with radical nephrectomy.
May support nephrectomy for localized renal liposarcoma; leaves open long-term outcomes and adjuvant needs.
Liposarcomas are malignant mesenchymal tumours usually located in the retroperitoneum, rarely occurring as a single lesion in the kidney. We present a case of a 59-year-old male patient with a left renal mass detected by computed tomography scan. He underwent radical nephrectomy and the histopathological study reported a primary undifferentiated liposarcoma of the kidney without nodal involvement. After 15 months of surgery, he remained asymptomatic and without evidence of disease recurrence. The objective of this report is to present a case and literature review with current evidence of treatment options and prognostic factors for survival.

Rioja et al. (2021) conducted a case report in Renal liposarcoma (n=1). Radical nephrectomy was evaluated on Disease recurrence. A 59-year-old male with primary undifferentiated renal liposarcoma remained asymptomatic and without evidence of disease recurrence 15 months after undergoing radical nephrectomy.
