- Abstract
Background: Renal sarcomas represent 1-2% of malignant kidney tumors in adults; 50% of renal sarcomas are composed of leiomyosarcomas. These tumors generally arise from the renal capsule, smooth muscle tissue of the renal pelvis and intrarenal vessels. They are indistinguishable from other renal masses prior to surgery and are associated with an adverse prognosis. Clinical case: We report the case of a 58-year-old female with a clinical course characterized by asthenia, weakness, generalized attack to her health status and pain in the left renal fossa. Computed axial tomography was performed where a left retroperitoneal tumor was diagnosed. Left radical nephrectomy was performed. The histopathology report demonstrated leiomyosarcoma originating from the renal sinus vessels. The patient was successfully treated with adjuvant radiotherapy. Conclusions: Renal leiomyosarcomas usually have an aggressive biological behavior with poor prognosis, accounting for surgical treatment with wide resection associated with adjuvant chemotherapy and radiotherapy as the only therapeutic option.
