Primary malignant tumors of the aorta are rare, only a handful of isolated cases having been described in the literature. Preoperative diagnosis of these tumors is more the exception than the rule. Diagnosis of aortic tumors is difficult as they can mimic many diverse conditions including atherosclerosis. We report a patient who presented with lower extremity claudication, renal infarction, and diffuse atherosclerosis and who was found to have tumor fragments in blood clots but no evidence of a primary tumor. Immunohistochemistry narrowed the differential diagnosis to a type of sarcoma. Six months later, he developed right flank pain due to a malignant fibrous histiocytoma that involved the abdominal aorta and that had initially manifested as tumor emboli.

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.

Malignant fibrous histiocytomas (MFH) as primary renal tumours are rare, with less than 50 cases described in the literature. We report a case of primary renal MFH of giant cell type in a 56-year-old man, who presented with bilateral dull flank pain, intermittent gross haematuria and body weight loss (6 kg in 3 months). Intravenous urography, computerized tomography (CT) and magnetic resonance image (MRI) showed right ureteral stones with mild hydronephrosis, and a solid mass at the lower pole of the left kidney associated with staghorn calculi, as well as tumour thrombi in the left renal vein and inferior vena cava. Left radical nephrectomy and evacuation of tumour thrombi from the left renal vein and inferior vena cava were performed. Histopathologic examination revealed malignant fibrous histiocytoma (MFH) of giant cell type. To the best of our knowledge, this is the first report of primary renal MFH associated with staghorn calculi.
