Renal Leiomyosarcoma with Mixoid Component: Case Report and Literature Review | Chapter 11 | Advanced Concepts in Medicine and Medical Research Vol. 1

 Primary leiomyosarcoma is an intensely rare entity establishing only 0.5–1% of all invasive renal tumors. It is commonly diagnosed after histological test because it does not have any distinguishing diagnostic countenance clinically and radiologically. At times, it is difficult to differentiate leiomyosarcoma from the sarcomatoid renal container carcinoma even all the while histological examination as both tumors have pivot-shaped atypical containers. Moreover, some epithelial tombstones can be present in pure smooth influence sarcomas, while some smooth muscle tombstones are positive in carcinomas. An intensely uncommon condition is leiomyosarcoma that develops in the renal stomach. A patient with an obstructive grain-related abandoned renal colic was admitted to ward with a filling defect in the renal stomach, which was originally misdiagnosed as a blood clot. After visual test of the renal pelvis and a examination of the exophytic lesion, leiomyosarcoma was determined expected the cause. Laparoscopic radical nephrectomy was performed, histological and immunohistochemical examination rooted the lesion expected a leiomyosarcoma with mixomatoid component. No adjuvant situation was performed, and the patient remains active 6 years later surgery without repetition. Herein we provide literature review, consideration of the diagnosis and situation scenario of the patient with renal stomach leiomyosarcoma with mixomatoid component.
