1/442. Complete response of a large brain metastasis of renal cell cancer to interferon-alpha: case report.

    BACKGROUND: interferon-alpha (IFNalpha) is a drug widely used in the treatment of metastatic renal cell cancers, especially lung lesions. Successful treatment using IFNalpha for histologically proven brain metastasis has not been reported. CASE REPORT: A large pineal tumor was found in a 51-year-old man with renal cell cancer in the left kidney. The histological diagnosis of biopsied specimens was a brain metastasis from renal cell cancer. The patient was treated with intramuscular injections of IFNalpha. The brain metastasis gradually decreased in size and disappeared completely 6 months after the initial injection of IFNalpha. The IFNalpha therapy was continued for 9 months. Fifteen months later, no recurrence was evident on brain magnetic resonance imaging. CONCLUSION: This is an extremely rare case in which the long-term use of IFNalpha induced a complete response of a brain metastasis from renal cell cancer.

2/442. Renal cell carcinoma with solitary synchronous pancreaticoduodenal and metachronous periprostatic metastases: report of a case.

    We report herein the case of a patient who underwent successful resection of a solitary metachronous periprostatic metastasis 12 months after undergoing a right radical nephrectomy with pylorus-preserving pancreaticoduodenectomy for renal cell carcinoma (RCC) with a synchronous pancreaticoduodenal metastasis. At present the patient is free of any signs of recurrence 12 months after removal of the metachronous mass in the periprostate. This case report supports the opinion that an aggressive surgical approach is appropriate for RCC metastasis.

3/442. A rare combination consisting of primary hyperaldosteronism and glucagonoma.

    A 59-yr-old man with multiple pancreatic tumors is presented. Previously, he had undergone left adrenalectomy for primary hyperaldosteronism and left nephrectomy for renal cell carcinoma at the ages of 39 and 55 yr, respectively. This time, 3 yr after removal of renal cancer, two solid lesions in the pancreas associated with hyperglucagonemia were detected. Under a diagnosis of pancreatic metastasis from renal cell carcinoma or islet cell tumor of the pancreas, distal pancreatectomy with splenectomy and enucleation of the tumor in the pancreas head were performed. Microscopically, a glucagonoma, measuring 2.3 mm in diameter, was detected among five pancreatic metastases from renal cell carcinoma. Four years after surgery, the patient remains well, without signs of recurrence despite multiple pancreatic metastases. This is the first report of such a rare combination consisting of aldosterone-secreting adrenal adenoma and glucagonoma.

4/442. Simultaneous contralateral testicular metastasis from a renal clear cell carcinoma.

    The case of a 66-year-old male with a right renal cell carcinoma and a left testicular mass is reported. Radical nephrectomy and contralateral orchidectomy were performed. histology revealed a metastasis of the renal cell carcinoma of clear cell type into the left testis. The patient died seven months post-operatively of disseminated lung metastases. The case demonstrates the multi-ocular metastatic potential of renal cell carcinoma.

5/442. Metastatic renal cell carcinoma mimicking pleural mesothelioma.

    Although it is well known that renal cell carcinoma metastasizes to the thorax, sole pleural metastasis is rare. We report a case of mesothelioma-like metastasis of renal cell carcinoma.

6/442. Pancreatic metastasis from renal cell carcinoma causing massive gastrointestinal bleeding in von hippel-lindau disease.

    patients with von hippel-lindau disease (VHLD) may develop pancreatic lesions, including cysts, serous cystadenomas and islet cell tumors. However, only a few cases of pancreatic metastasis have been reported. We present a case of VHLD with multiple pancreatic metastases from renal cell carcinoma. One of the metastases invaded the duodenum, causing massive bleeding.

7/442. A resected case of pancreatic metastasis from primary renal cell carcinoma.

    A 71-year-old man, who had received a right nephrectomy for a primary renal cell carcinoma 8 years earlier, and had two years later received a distal gastrectomy for duodenal ulcer, was admitted. In the subsequent clinical course, a solitary low echographical tumor was found in the pancreas. Abdominal computed tomography revealed a tumor of low density area, and celiac angiography revealed a hypervascular tumor stain of the pancreas. From the above findings, a diagnosis of pancreatic tumor was made, and a distal pancreatectomy was performed. Examination of the resected tissues confirmed the presence of a solitary tumor in the pancreatic tail. Histologically, the tumor corresponded to the initial renal cell carcinoma and pancreatic metastasis of renal cell carcinoma was diagnosed. We report a resected case of such a metastasis and review the literature.

8/442. Renal cell carcinoma: a rare source of cauda equina metastasis. Case report.

    The authors present the case of a patient in whom intradural metastasis from renal cell carcinoma spread to the cauda equina. To the authors' knowledge, this is only the second report of its kind. This male patient had undergone nephrectomy for the treatment of renal cell carcinoma for 5 years and was diagnosed as having metastatic lung disease 1 year prior to admission. The patient presented with lower back pain that radiated to both legs, but he exhibited no sensorimotor deficits. The majority of cauda equina tumors are primary tumors, and metastases are very rare. The literature is reviewed with reference to current molecular genetic paradigms of metastatic renal cell carcinoma.

9/442. Metastasis of a renal cell carcinoma to the nose and paranasal sinuses.

    We present a case of a metastasis of a renal cell carcinoma to the nose and paranasal sinuses. A 66 year old male patient developed a mass in his left nasal cavity and paranasal sinuses, five years after he underwent a left sided nefrectomy for a renal cell carcinoma. The histopathologic examination of the nasal mass showed metastasis of a renal cell carcinoma. A craniofacial resection was performed followed by radiotherapy.

10/442. Renal metastasis from prostatic adenocarcinoma: a potential diagnostic pitfall.

    We report a case of renal metastases from prostate cancer to show that the possibility of tumor metastasis, although rare, should always be considered in the differential diagnosis of renal mass.
