title: [Spontaneous rupture of malignant fibrous histiocytoma arising from the renal capsule: a case report].
abstract: We report a case of spontaneous rupture of malignant fibrous histiocytoma. A 50-year-old male with right flank pain was referred to our hospital. Computed tomography (CT) showed a heterogeneous space-occupying lesion on the upper pole of the right kidney. Selective right renal arteriography revealed a hypovascular mass. Preoperative clinical diagnosis was spontaneous rupture of renal cell carcinoma. Radical nephrectomy was performed. Histopathological diagnosis was malignant fibrous histiocytoma arising from the renal capsule.
