Primary Renal Angiosarcoma: A Case Report
摘要
Primary renal angiosarcoma is a high-grade malignant vascular tumor with a dismal prognosis. An 81-year-old woman with a primary angiosarcoma of the left kidney presented with a 3-month history of painless gross hematuria. On contrast-enhanced CT scans, the tumor was more infiltrative than that typically seen in renal cell carcinoma. Angiography, which was performed in order to differentiate a malignant tumor from an inflammatory mass, revealed a small number of tumor vessels and tumor stain. In addition to a radical nephrectomy, the patient received radiotherapy on the left renal fossa with a total of 4.35 Gy. Unfortunately, a follow-up sonogram revealed diffuse liver metastasis 6 months after surgery. Palliative chemotherapy including Ifosphamide and Mesna was given. However, hepatic failure complicate with hepatoencephalopathy developed during the 3rd course of chemotherapy. The patient died 9 months after nephrectomy. To our knowledge, this is the oldest reported patient with primary renal angiosarcoma.
