We report on 3 patients who presented with an acute onset of abdominal pain, a palpable abdominal mass and a rapid decrease in hemoglobin. In 2 patients a spontaneously ruptured hypernephroma was found and the other patient had a squamous cell carcinoma of the ureter with bleeding into the tumor. Although in all 3 cases the tumors were at an advanced stage of development, the patients had been entirely free of urological symptoms until shortly before hospitalization. The importance of considering the possibility of spontaneous rupture of such a tumor in the evaluation of cases of an acute abdomen is stressed.

A retrospective review of cases of renal adenocarcinoma during a five-year period revealed 6 cases with a papillary histologic organization. Closer examination indicates that papillary adenocarcinoma of the kidney is a slow-growing neoplasm with a clinical prognosis that appears to be considerably better than in other types of cellular organization.

A case of renal carcinoma with hepatic dysfunction and hypercalcemia is described. The literature on Stauffer's syndrome has been reviewed and the pathogenesis of this syndrome discussed. It is stressed that the presence of hepatic dysfunction should not be considered a contraindication to surgery since its manifestations have been observed to regress in many cases following removal of the tumor.

A new technique for inferior vena caval tumor thrombectomy is described. Vascular isolation of the cava from the right atrium to the pelvis is achieved by temporary circulatory arrest of the lower torso. Removal of the neoplastic thrombus under direct vision with minimal blood loss was accomplished in a patient with renal carcinoma, whose tumor extended into the intrapericardial vena cava.

It is possible to reproduce in vitro the induction in the leucocyte migration test of an immune response specific to hypernephroid carcinoma by preoperative radiation treatment of this neoplasm. The leucocyte migration is inhibited by soluble extracts of the tumor, prepared from hypernephroma-tissues (of 11 patients nontreated preoperatively) after in vitro irradiation either with electrons or with 60Co. This effect depends on the dose. The radiation dose producing a maximal inhibition following in vitro irradiation is nearly equal to that delivered by us before surgical treatment.

Based on the literature and own observations it is pointed out that in cases of vaginal tumors as a rule a consequent search for tumors of the kidneys is necessary, because vaginal tumors may be metastases of primarily not identified hypernephroid carcinomas. The frequency of such metastases is reported to be about 2%. A search for kidney tumors is necessary, if histological findings of the vaginal tumor are clearly suspect for hypernephroid carcinoma, or if it cannot be clearly identified as a primary vaginal tumor or--as a metastasis--gives no certainty to be a metastasis of a primary tumor of other localization. Because of the relative statistical frequency of vaginal metastases from carcinomas of the kidneys a consiliary gynecological check up is necessary if the diagnosis of the tumor was primarily a urologic one to ensure that there are no vaginal metastases. Further diagnostic and therapeutic procedures are discussed.

Renal cell carcinoma in pelvic kidneys is a surprisingly rare entity. This case report describes the first instance in which the tumor was delineated ultrasonographically. No clear rationale for this apparently lower incidence can be determined.

Sarcomatoid renal adenocarcinomas are rare, invariably fatal tumors. There is only one report of treatment of this tumor with chemotherapy. We report a case of an advanced sarcomatoid renal adenocarcinoma treated with chemoimmunotherapy consisting of cyclophosphamide, vincristine, Adriamycin (doxorubicin), DTIC, BCG, and sarcoma viral oncolysate. The patient had an objective response with a marked reduction in the size of the tumor mass. The residual tumor was removed surgically, and the patient remains in complete remission two years after the diagnosis was made.

A case study is presented of a 55-year-old man who had clear cell renal carcinoma with pulmonary metastases and erythrocytosis. The increase in red blood cell mass was associated with an elevation in erythropoietic stimulatory activity in serum, pleural fluid, and tumor-cyst fluid as determined by the exhypoxic polycythemic mouse assay. It is postulated that the increased erythropoietic stimulatory activity represents autonomous tumor secretion of erythropoietin or an erythropoietin-like material. Electron microscopic studies confirmed the proximal tubular origin of this tumor.

After sustaining very minor trauma, a man presented with flank pain and fever. A complete clinical and radiological evaluation led to exploration for suspected ruptured renal carbuncle with perinephric abscess. A ruptured renal cell carcinoma was found. Differential diagnostic considerations include renal tumor, abscess, cyst, and hydronephrotic kidney. Radical nephrectomy is indicated if the contralateral kidney can sustain life. The patient shows no sign of recurrence or metastases 4 months following antibiotic treatment and nephrectomy followed by chemotherapy and radiation of the renal bed.
