Primary lymphoma of the kidney is extremely rare; most lymphomatous renal masses represent extension from adjacent sites of disease or involvement by generalized disease (4,9,12). Three men and one woman, 45 to 71 years of age, presented with solitary renal masses clinically thought to be renal cell carcinoma. Each experienced abdominal pain, one with hematuria and one with "B" symptoms. Physical examination revealed no peripheral lymphadenopathy or hepatosplenomegaly. Lactic dehydrogenase (LDH) was elevated in three cases, and blood urea nitrogen (BUN) and creatinine were slightly increased in two. Two cases were diagnosed correctly from needle biopsy, with ultrastructural confirmation in one case and marker studies, DNA flow cytometry, and cytogenetics in the other. Because of a presumptive diagnosis of renal cell carcinoma, two patients underwent nephrectomy. Three cases were large-cell lymphoma, and one, small noncleaved cell lymphoma.

A 70-year-old woman with simultaneous unilateral renal angiomyolipoma and renal oncocytoma presented to the hospital with syncope and abdominal pain. Diagnostic studies indicated a left renal neoplasm consistent with renal cell carcinoma and a radical nephrectomy was performed. Histological examination of the resected specimen demonstrated the presence of the 2 unusual renal neoplasms.

Budd Chiari Syndrome, characterized by massive ascites, hepatomegaly, abdominal pain, and tenderness, nausea, and vomiting, is caused by obstruction of the hepatic venous outflow. Of the known causes of polycythemia rubra vera, hypernephroma, and other tumors invading the inferior vena cava have been most often reported, while pregnancy and oral contraceptives (OCs) have also been held as causes. In this paper the case is presented of a young woman, previously on OCs for 4 months, who developed the syndrome 2 weeks after delivery; she was also found to have multiple hepatic adenomas on laparotomy. The longterm use of OCs has been estimated to be associated with an annual incidence of liver cell adenoma of 3-4/100,000. Evidence suggests that the estrogen components, rather than the progesterone, of OCs seem more likely to cause liver cell adenoma since estrogens are carcinogenic in other organs and promote liver cell regeneration in rats. By interference with the metabolism of oncogenic bile salt derivatives, estrogen may exert its oncogenic effect. The patient is this case was told never to use OCs again since there is also evidence that the tumor may regress on stopping OCs, and she was advised against further pregnancies.

Nontraumatic renal subcapsular hematoma is an uncommon but not rare clinical entity. If a small renal cell carcinoma is the cause of the hematoma, the carcinoma can hardly be diagnosed on the basis of conventional roentgenographic findings. Computerized tomography provides a noninvasive means of visualizing the hematoma and renal tumor, and of understanding their extent, location and relationship to renal parenchyma. A 42-year-old female, whose complaint was right abdominal pain and vomiting, was admitted to our hospital and a right renal subcapsular hematoma was demonstrated by computerized tomography. She was in good general condition, and renal malignant tumor was not demonstrated by computerized tomography, conventional roentgenographic examinations or ultrasonography. Her clinical course was not eventful . A brief review of clinical diagnosis and management of this disease are made.

Phase II study of cis-diaminedichloroplatinum(II) (CIS-DDP) administered intravenously was performed in 77 patients with urologic malignancies for the evaluation of clinical responses and adverse effects. The eligibility of the patients and evaluation of response were carried out according to the general criteria proposed by Drs. Koyama and Saito. Out of 85 patients, entered in this phase II study, 77 patients were considered evaluable. Complete responses were seen in 4 patients, 3 testicular tumor and 1 bladder cancer. Partial response were obtained in 24 patients; 10 bladder cancer, 8 testicular tumor, 5 prostatic cancer, and 1 renal cell carcinoma. Overall response rates were 73.3% in testicular tumor, 50.0% in bladder tumor, 20.8% in prostatic cancer, and 7.7% in renal cell carcinoma. Incidences of toxicities were noted in the gastrointestinal tract. Nausea, vomiting, anorexia, abdominal pain, and diarrhea were observed in 78.5% of the patients treated with CIS-DDP. Myelosuppression, lassitude, renal and hearing dysfunction were other prominent adverse effects.

We present a case of renal subcapsular hemorrhage caused by a small renal cell carcinoma. The patient was a 52-year-old housewife, presenting abdominal pain and vomiting, of abrupt onset. Modern imaging modalities clearly visualized a perirenal or subcapsular hematoma in her left kidney, but no underlying pathology, was found even on the arteriogram. Relying on the statistics based on more than 100 reported cases with the spontaneous renal rupture, nephrectomy was carried out. The renal carcinoma was of granular cell type (G2), and classified as pT2, pN0 and pM0. Difficulties in making a correct diagnosis as to the pathology and therefore a rational decision for nephrectomy were also stressed.

Renal oncocytoma is an uncommon tumor. Of 223 renal tumors that were treated at our institution from 1970-1991, 14 (6.2%) were oncocytomas [9 females (65%) and 5 males (35%)]. The highest incidence was observed in the sixth decade (60.7 yrs). Tumor size range from 2 to 19 cm in diameter (mean = 8.07 cm); 11 (78.5%) were localized in the right kidney, principally in the superior pole. The tumor was incidentally discovered in 8 cases (57%); 1 case presented Wunderlich's syndrome; 1 had a palpable renal mass; 6 had abdominal pain. All the tumors were confined to the kidney. Thirteen were Robson stage I and 1 stage II. According to the UICC classification, 12 were T1, 1 T2 and 1 T3. All tumors were N0 M0. Patient evaluation included IVP (6), US (12), CT (14) and selective renal arteriography (2). The typical angiographic patterns were not observed in these 2 cases. Concerning the CT findings, in 8 cases (57%) the first diagnosis discarded was that of hypernephroma, although there were also signs suggestive of oncocytoma. Six cases (43%) showed signs indicating oncocytoma as first diagnosis. All patients were submitted to radical nephrectomy, which achieved good results in all cases at 7 months' to 5 years' follow up.

Most patients who present with a large solid renal mass and evidence of advanced malignancy will have primary renal cell carcinoma but a small subset with similar features have different and more treatable malignancies. We identified 7 patients with clinical and radiological findings suggestive of metastatic renal cell carcinoma who were ultimately diagnosed as have non-Hodgkin's lymphoma (5), germ cell tumor (1) or transitional cell carcinoma (1). Two of these patients presented with abdominal pain, gross hematuria and a flank mass. Computerized tomography was interpreted as showing renal cell carcinoma in all patients, although lymphoma and sarcoma were included in the differential diagnoses in 2. With the correct diagnosis and appropriate therapy, 4 of the 7 patients are currently disease-free. We emphasize the need for histological documentation in such patients in view of curative therapy available for possible underlying neoplasms simulating renal cell carcinoma.

There have been a few reports on the spontaneous rupture of renal cell carcinoma. A 67-year-old female patient complaining of vomiting and severe abdominal pain was referred to our hospital. Plain computerized tomography demonstrated large heterogenous mass in the right retroperitoneum. We suspected the hemorrhagic shock because of the rupture of the right kidney and therefore emergent laparotomy was performed. Simple nephrectomy for the right kidney was performed. A pathological report revealed renal cell carcinoma, granular cell subtype, grade 1, pT3a. The patient has been followed for one year and five months after the operation, there has been no evidence of local recurrence or distant metastasis of cancer. Thirteen cases of spontaneous rupture of renal cell carcinoma in the Japanese literature are reviewed.

Lesions of the anterior mediastinum typically include neoplasms of the thymus or thyroid, hemangioma, germ cell neoplasms, lymphoma and others. Renal cell carcinoma often presents with flank pain, hematuria, abdominal pain and/or fever. Chest cavity involvement by renal cell carcinoma typically manifests as pulmonary parenchymal disease with or without hilar lymph node involvement. We report an unusual presentation of renal cell carcinoma in a patient who presented with symptoms secondary to a large anterior mediastinal mass. A 64-year-old woman came to the hospital complaining of malaise, cough, dyspnea, weight loss and night sweats. Chest roentgenogram and computed tomography revealed a large anterior superior mediastinal mass without significant pulmonary parenchymal disease. She was also noted to have microscopic hematuria and a renal mass was found. Histology of both masses revealed renal cell carcinoma. This case suggests that renal cell carcinoma may merit consideration in the differential diagnosis of an anterior mediastinal mass and illustrates an unusual manner by which this lesion may present.
