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 .
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.
Transitional cell carcinoma is an even rarer entity, in which neoplastic transitional epithelial cells similar to transitional cell carcinoma of the bladder are seen in the ovary, without the characteristic stromal/epithelial pattern of a Brenner tumour.
Transitional cell carcinoma is the most common form of cancer in the lower urinary tract—the bladder and urethra. This video discusses the pathophysiology, signs and symptoms, diagnosis, and treatment of transitional cell carcinoma.
Ureteral cancer is usually a transitional cell carcinoma. [2] [4] Transitional cell carcinoma is "a common cause of ureter cancer and other urinary (renal pelvic) tract cancers." [1] Because the inside of the ureters and the inside of the bladder contain the same cell type, people who have been diagnosed with ureteral cancer are more likely to ...
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 ...
The most common histology seen in primary urethral cancer (a cancer which originates in the urethra, as opposed to cancer cells from elsewhere in the body which metastasize to the area) is urothelium, a type of transitional epithelium. Urothelial cell cancers comprise just over half of primary urethral cancers.
Buttock cells are cells having a notched appearance that are found in certain malignancies, [1] such as non-Hodgkin's lymphoma (including follicular lymphoma), [2] [3] mycosis fungoides, [4] and Sézary syndrome.
