Email this article A Case of Leiomyosarcoma of the Kidney
Abstract
Introduction: Sarcomas of the kidney are rare. Among primary sarcomas, leiomyosarcoma is the most frequent. A case of primary renal leiomyosarcoma is presented.
Case report: This report concerns a 48 year old women, who presented with slowly increasing right flank mass and dull aching pain. A well defined, gray, firm mass measuring 12.5x10.5 cm was histologically composed of interlacing bundles of spindle cells with cellular atypia and nuclear hyperchromasia. Mitotic figures constituted 10-12/10 HPF. Tumor cells showed positivity for desmin. The differentiation from sarcomatoid renal cell carcinoma is discussed.
Conclusion: The case is reported for its rarity and this is the first reported case of renal leiomyosarcoma in Nepal.
