Urothelial cells are part of the urothelium surrounding the urethra, bladder, prostate and pelvis, according to the University of Chicago Medicine and Biological Sciences. Bladder cancer is the most common form of cancer in this type of cell. Some screening tests show atypical cells when no serious illness is present.
The ability to consistently diagnose low-grade urothelial neoplasia (LGUN) in urinary cytologic specimens remains controversial. Cytologically, we cannot unequivocally distinguish among the different types of LGUN such as urothelial papilloma, papillary urothelial neoplasms of low malignant potential (PUNLMP), low-grade papillary urothelial carcinoma (LGPUC), as well as flat low Definition.

Non‐urothelial carcinomas involving the bladder are uncommon and often diagnostically challenging. These carcinomas may show squamous, adenocarcinomatous or neuroendocrine features, with immunohistochemical stains aiding the diagnosis in only a subset of cases.

High-grade invasive tumors are less common and have a much poorer prognosis. Squamous cell carcinoma and adenocarcinoma occur in the setting of chronic bladder infection and irritation.
