primitive neuroectodermal tumor (pnet) is usually an aggressive, rapidly progressing and metastasizing tumor. occurrence of this type of tumor in the kidney is considered as unusual and few cases have been reported so far. we present a metastatic pnet arising probably from the kidney in a 17-year-old female patient with local invasion and metastasis to the stomach. pnet should be considered as ...

a man with metastatic carcinoma of the colon had a bone scan which revealed urinary retention in the leftkidney. ten months later, a tc-99m-dtpa renai glomerular study showed the left kidney to have only 8% oftotal renal function. fifteen months after that, (he same kidney demonstrated 9% of total function, while theright kidney had evolving obstruction due to his neoplasm. the case shows that ...

Diabetes has been reported to increase the risk of malignant neoplasms of kidney and bladder, but the studies' results are still inconclusive. Age, sex, and geographical area-specific incidence and relative risks of above neoplasms are also scarce in the literature. We prospectively investigated the age, sex, geographical area-specific incidence and relative risks of kidney and bladder neoplasm...

cAsE A 29-year-old female patient was admitted after a computed tomography (CT) scan showing a neoplasm measuring 4.5×4.0×4.5cm located in the middle and dorsal part of the left kidney (Figure-1). In the CT plain scan phase, the neoplasm had almost equal density with the normal kidney, and the CT unit was 45. It had a clear boundary, and part of the neoplasm extruded the renal contour. A multip...

BACKGROUND The kidney recipient is at a higher risk for cancer than is the general population, although the incidence of neoplasms in general is considered lower in Japan than in Western countries. The cause of this increased risk associated with either transplantation or geography has not yet been established. METHOD The incidences and sites of malignant neoplasms were analyzed in 285 kidney...

conclusions radical nephrectomy and tumor thrombectomy by intrapericardial control without cardiopulmonary bypass and hypothermic circulatory arrest is a safe and effective procedure that can avoid serious intra- and postoperative complications while providing acceptable cancer-control and mortality results. case presentation the records of six patients with supradiaphragmatic tumor thrombi, wh...

Renal transplantation is considered one of the best long-term therapies for chronic renal failure, but unfortunately the incidence of malignancy significantly increases in renal transplant recipients. We analyzed nine cases of malignancy in 200 renal transplant recipients occurring in a 12-year follow-up in Imam hospital of Tehran University, Tehran, Iran. According to this study, the organ...
