Background: Definite data regarding the incidence and distribution of renal tumours in eastern India is not known. For better management, as it is essential to identify patients with poor prognosis, prognostic factors like stage, nuclear grade and their relationship to molecular markers are also unclear in this region. The purpose of our study was to assess the spectrum of adu...
background: definite data regarding the incidence and distribution of renal tumours in eastern india is not known. for better management, as it is essential to identify patients with poor prognosis, prognostic factors like stage, nuclear grade and their relationship to molecular markers are also unclear in this region. the purpose of our study was to assess the spectrum of adult renal tumours w...
Introduction A variety of benign and malignant tumours can arise in the kidney in children. With minor variations, the spectrum of tumours has worldwide distribution. Wilms’ tumour (WT; also known as nephroblastoma) is the most common kidney tumour in childhood, and may represent the most common abdominal tumour presenting in infants and children in sub-Saharan Africa. In the past decade, consi...
Six peroxidase conjugated lectins were used to compare their ability to bind to formalin fixed paraffin embedded tissue sections of childhood renal tumours (Wilms' tumour, mesoblastic nephroma, renal carcinoma, rhabdoid renal tumour, and bone metastasising renal tumour of childhood (BMRTC) with fetal and normal children's kidney. Lectins were found to be helpful in the differential diagnosis of...
Low-grade oncocytic tumour (LOT) of the kidney is one emerging entities included in recently published Fifth Edition WHO classification Tumours.1 It shows overlapping morphological features with oncocytoma and chromophobe renal cell carcinoma but has unique KIT negative Keratin (KRT) 7 diffuse positive immunophenotype. Herein, we describe clinical, morphological, immunohistochemical findings tw...
Context. Primary renal carcinoid tumours are rare. Their pathogenesis is unknown and the clinical presentation is similar to other renal tumours thus posing diagnostic dilemmas for clinicians. Objectives. To review the literature for case reports of primary renal carcinoids. Methods. Literature was extensively searched for case reports for primary renal carcinoids. Reports of metastatic carcino...
Renal carcinoma is a common and aggressive malignancy whose histopathogenesis is incompletely understood and that is largely resistant to cytotoxic chemotherapy. We present two mouse models of kidney cancer that recapitulate the genomic alterations found in human papillary (pRCC) and clear cell RCC (ccRCC), the most common RCC subtypes. MYC activation results in highly penetrant pRCC tumours (M...
Fine needle aspiration cytology (FNAC) is used for preoperative diagnosis of paediatric renal tumours, especially in centres where preoperative chemotherapy is advocated in Wilms' tumour. This review focuses on salient cytological features in specific paediatric renal tumours, the approach to resolving a differential diagnosis and the role of ancillary methods in diagnosis of paediatric renal t...
The clinical and pathological features of multiple different renal neoplasms arising in a setting of end-stage renal disease in a 72-year-old male are described. The kidney showed features of renal oncocytosis with multiple oncocytomas, hybrid tumours and chromophobe renal carcinoma. In addition, the kidney contained a type 2 papillary renal cell carcinoma, clear cell papillary and cystic renal...
