Case 1. A 61 year old man complaining of a Gross painless hematuria. On urologic examinations, the right kidney was considered normal. The left had a tumor. The left kidney was thus removed (the weight 1290gms), which was proven histologically to be a fibrosarcoma. The patient died of the postoperative relapse 9 months after the surgery. Case 2. A 55 year old man complaining of hypochondrial hard tumor in the left side. No hematuria. Urologic examinations including urography revealed a tumor in the left kidney. The left kidney was thus removed (the weight 420gms), which was proven histologically to be a reticulosarcoma. Following the nephrectomy, the tumor metastasis appeared on the costas, the tonsils, the lower abdominal cavity, and the superficial lymphglands. The patient died after 42 days postoperatively. Lavoratory studies showed neutrophilic leucocytosis to be in the level of 50,000/cmm throughout the course of the disease.
