چکیده
Leiomyosarcoma (LMS) is a rare malignant tumor of smooth muscle origin that generally stems from soft tissues and uterine tissue. Although, a small percentage of these may originate from the smooth muscle or vessel walls, most of which are of venous origin. Renal leiomyosarcomas may arise from the smooth muscle fibers of renal pelvis, renal capsule or renal vessels, last one is the most frequent. We report a case of renal LMS that could be originated in the renal capsule.

Primary Leiomyosarcoma of the Kidney : A Case Report and Review of Literature
Primary sarcomas of the kidney are exceptional. Among renal sarcomas, leiomyosarcoma is the most common histologic subtype amounting to 50-60% of all cases. The tumor usually arises from either the renal capsule or smooth muscle tissue in the renal pelvic wall. In this paper, we report a patient with leiomyosarcoma of the kidney presented with non-specific abdominal pain and a palpable mass....
متن کاملA Case of Renal Metastasis of Uterine Leiomyosarcoma
A 49-year-old woman with a distant history of uterine leiomyosarcoma underwent robotic-assisted laparoscopic partial nephrectomy for a 3.5 cm right renal mass, which was presumed to be a primary renal cell carcinoma. Surgical margins were negative, and the histologic analysis confirmed leiomyosarcoma. Uterine leiomyosarcoma is traditionally a locally aggressive disease with only rare reports of...
متن کاملRecurrent Renal Leiomyosarcoma Mimicking a Colonic Submucosal Tumor: A Case Report
A primary leiomyosarcoma of the kidney is a rare, but highly aggressive, neoplasm, accounting for only 0.1% of all invasive renal tumors. Local or systemic recurrence is common, but a leiomyosarcoma is difficult to diagnose preoperatively. We recently encountered an interesting case of an unusual recurrence of a renal leiomyosarcoma. A 57-year-old woman visited our hospital complaining of lower...
متن کاملLeiomyosarcoma Arising from the Blind End of a Bifid Renal Pelvis
Sarcoma of the kidney is a rare condition. Leiomyosarcoma is the most common of the kidney sarcomas. Renal leiomyosarcoma usually originates from the smooth muscle layers of the kidney, for example, the renal capsule and renal vessels. Renal pelvis neoplasms, however, are primarily transitional cell carcinomas, and renal pelvis leiomyosarcomas are extremely uncommon. Renal pelvis leiomyosarcoma...
متن کاملLeiomyosarcoma of the renal vein.
Leiomyosarcoma of the renal vein is a rare tumor of complex diagnosis. We presented a case of renal vein leiomyosarcoma detected in a routine study. The primary treatment was complete surgical removal of the mass. In cases where surgical removal is not possible the prognosis is poor, with high rates of local recurrence and distant spread.
