It is especially recommended when blood in the urine has been detected. Urine typically contains epithelial cells shed from the urinary tract, and urine cytology evaluates this urinary sediment for the presence of cancerous cells [ 2 ] [ 3 ] from the lining of the urinary tract, and it is a convenient noninvasive technique for follow-up ...
Urothelial cell cancers comprise just over half of primary urethral cancers. Roughly another quarter of cases are squamous cell carcinomas, and the majority of the remainder are adenocarcinomas, which originate from the cells of various secretory glands in and around the urethra. Up to 10% of primary urethral cancers have variant histology ...
Urachal cancer is a very rare type of cancer arising from the urachus or its remnants. [1] The disease might arise from metaplastic glandular epithelium or embryonic epithelial remnants originating from the cloaca region. [2] It occurs in roughly about one person per 1 million people per year varying on the geographical region. [3]
Bladder tumors are classified by their appearance under the microscope, and by their cell type of origin. Over 90% of bladder tumors arise from the cells that form the bladder's inner lining, called urothelial cells or transitional cells; the tumor is then classified as urothelial cancer or transitional cell cancer.
Decoy cells owe their name to their strong resemblance to cancer cells, and may as such confuse the diagnosis of either viral infection or urothelial malignancy. During 1950s, cytotechnologist Andrew Ricci observed cells mimicking cancer cells by they were not, in a group of persons working in some kinds of industries - they were referred to as ...
Invasive urothelial carcinoma is a type of transitional cell carcinoma. It is a type of cancer that develops in the urinary system: the kidney , urinary bladder , and accessory organs. Transitional cell carcinoma is the most common type of bladder cancer and cancer of the ureter , urethra , renal pelvis , the ureters , the bladder , and parts ...
Transitional cell carcinoma is a type of cancer that arises from the transitional epithelium, a tissue lining the inner surface of these hollow organs. [1] It typically occurs in the urothelium of the urinary system ; in that case, it is also called urothelial carcinoma .
Atypical hemolytic uremic syndrome (aHUS), also known as complement-mediated hemolytic uremic syndrome (not to be confused with hemolytic–uremic syndrome), is an extremely rare, life-threatening, progressive disease that frequently has a genetic component. In most cases, it can be effectively controlled by interruption of the complement cascade.
