Leiomyosarcoma: A rare renal tumor

Abstract:

Introduction: Renal leiomyosarcoma is a rare tumor constituting 0.12% of all malignant renal neoplasms; the clinical presentation is highly variable. Clinical case: We report the case of a 68 year old man who presented with right back pain; CT scan (computed tomography) showed a large mass located at upper pole of the right kidney. We performed a radical nephrectomy and resection of a right basal lung node incidentally found, the histopathological and immunohistochemical diagnosis was a renal high-grade leiomyosarcoma with metastases to the lung.
