title: [A case of retroperitoneal liposarcoma arising from the renal capsule].
abstract: We treated a case of retroperitoneal liposarcoma arising from the renal capsule by operation and adjuvant radiation. A 61-year-old woman was referred to our department for treatment of a right renal tumor revealed by computed tomography (CT). CT, magnetic resonance imaging and angiography demonstrated a large renal tumor with fat tissue, fed from the renal capsular artery. Right radical nephrectomy was performed on February 4, 2003. The tumor was diagnosed histopathologically as well differentiated liposarcoma arising from the renal capsule. The surgical margin was positive. Therefore, the patient was given 50 Gy of radiation postoperatively. There have been only 18 reports of liposarcoma arising from the renal capsule in Japan.
