Cat with chronic kidney disease and typical symptoms: fatigue, emaciation and dull, shaggy coat. The chronic kidney disease of the cat (CKD or CNE) – also called chronic renal insufficiency (CRI or CNI) or chronic renal failure (CRF) in the older literature – is an incurable, progressive disease characterized by a gradual decrease in the nephrons and thus to a decreasing function ...
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
Mammary gland tumors are the third common type of cancer in older female cats, with the most common symptom manifesting as a lump in the breast tissue. [3] Domestic short-haired cats and Siamese appear to have a higher incident rates. [10] The tumor is typically firm and nodular, and adheres to the overlying skin. [11]
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 ...
Treatment for kidney cancer depends on the type and stage of the disease. Surgery is the most common treatment as kidney cancer does not often respond to chemotherapy and radiotherapy. Surgical complexity can be estimated by the RENAL Nephrometry Scoring System. If the cancer has not spread it will usually be removed by surgery.
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.
Multilocular cystic renal cell carcinoma (MCRCC) is rare subtype of renal cell carcinoma. Histologically, the tumor has a fibrous capsule and contains multiple cysts with clear cells. [1] 1-5% of renal cell carcinomas are MCRCC. [1]
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]
