High-Grade Primary Leiomyosarcoma of the Kidney

Abstract

Leiomyosarcomas account for 0.8 to 2.7% of all malignant renal tumors. Like the leiomyomas, the leiomyosarcomas originate from the cells of the renal capsule, pelvis renalis, the calyces and smooth muscle of the blood vessels. They are two-folds more common in women and most frequently seen in the fourth and sixth decades. They are solitary lesions. Their major symptoms are pain, palpable mass and hematuria. Clinical, radiological and pathological findings of a 51 years old patient presenting with diagnosed flank pain and nausea and diagnosed as having high-grade primary renal leiomyosarcomas were evaluated under the light of current literature.
