We report a case of multiple gastric carcinomas associated with Potter type III cystic disease of the liver, mesenterium and kidney. A 65-year-old man with chronic renal failure due to polycystic kidneys and under hemodialysis treatment 3 times a week for 2 years was admitted to our hospital because of anemia. He stated that his sister had suffered from polycystic kidney disease. Gastrointestin...

Streptozotocin, an antibiotic widely used for induction of diabetes in experimental animals and for the treatment of pancreatic neoplasms, was shown to be a potent methylating agent reacting with DNA in vitro to form methylated purines. The reaction was similar in extent and relative proportions of methylation products to that produced by /V-methyl-N-nitrosourea, the aglycone of Streptozotocin....

Purpose: The purpose of the present study was to examine roles new proteins DARS2, Reelin, and Encurin in differentiation Clear-Cell Renal Cell Carcinoma (RCC) Papillary (RCC). Clear-cell RCC is most common malignancy kidney, papillary second malignant this respect. They are neoplasms show similarity each other, both histologically morphologically, some cases. Differential diagnosis important b...

Background: Low-grade oncocytic tumour (LOT) is an emerging entity describing a slow growing with morphologic features overlapping between chromophobe renal cell carcinoma (ChRCC) and oncocytoma, staining positive for cytokeratin-7 negative CD117 (c-kit). This has been recently recognised in the WHO classification of tumours 5th edition 2022. Presentation: In this case report, we present 77-yea...

The main primary childhood renal neo-plasms are nephroblastoma, mesoblastic ne-phroma, clear cell sarcoma, and rhabdoid tumour. Other primary renal neoplasms include primitive neuroectodermal tumour (PNET), renal cell carcinoma, and angiomy-olipoma. Nephroblastoma is the most common renal tumour in children. It is a complex embryonal tumour of metanephric blastemal derivation, which often conta...

The most recent World Health Organization classification of renal neoplasms encompassed nearly 50 distinctive renal neoplasms. Different histological subtypes have different clinical outcomes and show different responses to therapy. Overall, the incidence of kidney cancer has increased worldwide in the last years. Although the most common type of kidney cancer is localized renal cell carcinoma ...

A significant dose-response relation between ingested arsenic and several cancers has recently been reported in four townships of the endemic area of blackfoot disease, a unique peripheral artery disease related to the chronic arsenic exposure in southwestern Taiwan. This study was carried out to examine ecological correlations between arsenic level of well water and mortality from various mali...

BACKGROUND AND OBJECTIVES Partial nephrectomy or radical nephrectomy is the standard of care for patients with kidney neoplasms, but surgery may result in loss of renal function. We sought to identify patient characteristics associated with renal functional recovery following radical nephrectomy. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We performed a retrospective study among 572 patien...

Sarcomatoid squamous cell carcinomas are extremely rare, high grade, aggressive variant of penile cancers. Sarcomatoid carcinoma are biphasic neoplasms with a combination of both sarcomatoid components and carcinomatous elements. These neoplasms are very rare in the urogenital system. We report a 53-year-old male presented with an ulcerated lesion on the glans penis. The rarity of this case rei...
