“…Like other renal sarcomas, LPSs remain clinically asymptomatic till they are large. Common presenting symptoms include pain, hematuria, abdominal mass, or loss of weight (35). Histologically, LPSs have been classified as myxoid (60%), well-differentiated (25%), and pleomorphic (10%) types; the majority of published cases of primary LPSs are well-differentiated tumors (35).…”

There is a wide pathological spectrum of kidney sarcomas that show characteristic histology, ontogeny, and clinical-biological behavior. While leiomyosarcomas commonly arise from the capsule, solitary fibrous tumors and clear cell sarcomas typically show renal sinus and medullary epicenter, respectively. Although distribution and imaging findings of some sarcomas may be characteristic, definitive diagnosis warrants histopathological examination following surgery. Renal sarcomas manifest advanced disease at presentation and portend poor prognosis.

“…Renal sarcoma is a rare malignancy that occurs in only 1% of all kidney cancer. 1,2 Wang et al analyzed 41 cases of renal sarcoma from 1989 to 2009. The most common histological subtype was leiomyosarcoma in 16 patients (39%), followed by liposarcoma in 12 (29.3%), and other in 13 (31.7%).…”

Key Clinical MessageRenal sarcoma is a rare and aggressive malignancy without proper guidelines for treatment. Due to the aggressiveness of this disease and the potential for recurrence, we believe that extensive surgical resection with healthy margins may be the best option to treat this condition during both initial resection and resection of the recurrent lesion. Clinical follow‐up is also important to monitor for tumor recurrence.

“…1 The natural behavior of and outcome of STS are dependent of the age of the patient, anatomical site and depth, size, and resectability of the tumor, as well as of histology, grade , nodal disease and distant metastasis. 6 Most RLS, even of important size, rarely metastasize. 1 They occur generally in the 4 th and 6 th decades of life.…”

oft tissue sarcomas (STS) are rare and locally invasive tumors.The most common type of soft tissue sarcomas is liposarcomas. It consists of <1% of all malignant tumors in adulthood.1,2 Retroperitoneal liposarcoma (RLS), is a rare, biologically heterogeneous tumor that presents considerable challenges due to its size and deep location.1 85% of RLS are malignant tumors that remain occult for long periods and grow quite large. Their typical symptoms are discomfort, pain or a palpable mass due to large size. These tumors occur most frequently in men, generally in the fifth or sixth decade of life. Magnetic resonance imaging (MRI) provide reliable data about localization of mass and relationship between vascular structures. Although complete surgical resection is mandatory for extending survival, the majority of patients with huge RLS will develop locally recurrent disease following surgery. [1][2][3] So that patients should be followed routinely in every 3 months during first two years . 4 Pleomorphic liposarcoma is the rarest subtype and is a high grade tumor. The risk of recurrence and metastatis with liposarcoma increases with higher grade. Herein, we report a case of a 68 year-old man with a 35 cm mass adjacent to kidney with synchronous inguinal 7 cm mass. CASE REPORTA 68 year-old man, who had been suffering from progressive enlargement and discomfort of abdomen with weight loss during last 3 months.Other past medical and familly histories were unremarkable. On physical examination, a palpable mass on the right flank was found. The abdomen was extremely swollen, tense and dilated veins were apparent over abdomen. A AB BS S T TR RA AC CT T Retroperitoneal liporsarcoma (RLS) is a rare, highly malignant tumor with poor prognosis and high recurrence rate. Pleomorphic liposarcoma is the rarest subtype and is a high grade tumor with cells with very different appearance from normal cells.Herein we report a case of a 68 year-old man with a 35 cm mass adjacent to kidney with synchronous inguinal 7 cm mass. The patient was operated in our clinic and pathology revealed plemorphic liposarcoma. The case was discussed because of its rarity and two mass in the two distinct region.K Ke ey yw wo or rd ds s: : Retroperitoneal liposarcoma; liposarcoma; nephrectomy
