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 Paris System for reporting urinary cytology, version 2.0, ranging from negative to positive for high grade urothelial carcinoma (HGUC). [11] Transitional refers to the histological subtype of the cancerous cells as seen under a microscope. Immunohistochemistry for p53 can help distinguish a PUNLMP from a low grade urothelial carcinoma ...
Primary urethral cancer is rare and contributes to less than 1% of all cancers. It is three times more common in men than women and its incidence rises after the age of 75. [1] Around half of affected people have locally advanced disease when they first present. 54–65% of cases are of the urothelial carcinoma type. [1]

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.
They undergo glandular metaplasia, a process in which irritated tissues take on a different form, in this case that of a gland. [1] The main importance is in the findings of test results, in this case histopathology. They must distinguish a benign metaplastic change from the cancerous condition urothelial cell carcinoma. [2]
The Paris System for reporting urine cytology, version 2.0, ranging from negative to positive for high grade urothelial carcinoma. [1] Urine cytology is a test that looks for abnormal cells in urine under a microscope. The test commonly checks for infection, inflammatory disease of the urinary tract, cancer, or precancerous conditions.
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]
