The RENAL Nephrometry Scoring System is used to measure the complexity of kidney tumors for determining whether a renal mass is appropriate for partial or radical nephrectomy, and is estimated by CT scan as follows: [7] The nephrometery score takes into account the size of the tumor (Radius), how much of the tumor is inside or outside of the ...
Cystic kidney disease refers to a wide range of hereditary, developmental, and acquired conditions [1] and with the inclusion of neoplasms with cystic changes, over 40 classifications and subtypes have been identified. Depending on the disease classification, the presentation may be at birth, or much later into adult life.
Sarcoma- for example leiomyosarcoma, liposarcoma, angiosarcoma, clear-cell sarcoma and rhabdomyosarcoma are types of sarcomas that have occurred in the kidney; Metastatic tumor from distant organ; Lymphoma; Wilms tumor- an embryonic tumor that is the most common type of kidney cancer in children; Carcinoid tumor of the renal pelvis [37 ...
The type of treatment depends on multiple factors and the individual, some of which include the stage of renal cell carcinoma (organs and parts of the body affected/unaffected), type of renal cell carcinoma, pre-existing or comorbid conditions and overall health and age of the person.
Histopathologic types of kidney tumor, with relative incidences and prognoses. Cystic nephroma is seen at bottom right in pie chart. cystic partially differentiated nephroblastoma; cystic standard nephroblastoma (cystic Wilm's tumor) cystic mesoblastic nephroma; cystic renal cell carcinoma; other renal cysts
Papillary renal cell carcinoma (PRCC) is a malignant, heterogeneous tumor originating from renal tubular epithelial cells of the kidney, which comprises approximately 10-15% of all kidney neoplasms. [1] Based on its morphological features, PRCC can be classified into two main subtypes, which are type 1 and type 2 (eosinophilic). [2]
Gross appearance of a renal oncocytoma (left of image) and a slice of a normal kidney (right of image). Note the rounded contour, the mahogany colour and the central scar. In gross appearance, the tumors are tan or mahogany brown, well circumscribed and contain a central scar. They may achieve a large size (up to 12 cm in diameter).
The renal cell carcinoma tends to be of the papillary (type 2) form and tends to occur more commonly in women than men with this syndrome. These cancers present earlier than is usual for renal cell carcinomas (typically in the twenties and thirties) and tend to be at relatively advanced stages at presentation.
