Papillary urothelial neoplasm of low malignant potential of the urinary bladder: clinicopathologic and outcome analysis from a single academic center Few long-term single-center studies have addressed the outcome of patients with papillary urothelial neoplasms of low malignant potential. 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-grade urothelial dysplasia. In addition, some urothelial carcinomas show basal/squamous differentiation, which has been associated with poorer prognosis [12–14]. The immunohistochemical staining pattern for cytokeratin20 and CK5/6 varies with the type and nature of the urothelial neoplasm. Definition.
It develops within a type of cell in the inner lining of the bladder, ureters, and lower kidneys. The bladder is a muscular organ in the Examples of benign‐appearing urothelial tissue fragments found in voided urine specimens taken from patients (A‐D) without subsequent urothelial neoplasia on follow‐up (Papanicolaou stain, ×400), (E and F) low‐grade urothelial carcinoma on follow‐up (Papanicolaou stain, ×400), and (G) papillary urothelial neoplasm of low malignant potential on follow‐up (Papanicolaou stain, ×400 The last decade has seen a tremendous upheaval in the very important area of urothelial neoplasm classification, which only recently seems to have settled down to a level of general concurrence. Urothelial proliferation of unknown malignant potential (UPUMP) is a 2016 World Health Organization classifier that encompasses prior categories of flat and papillary urothelial hyperplasia. In addition, UPUMP occurs in settings of both de novo and prior bladder neoplasia. Urothelial neoplasm, or transitional carcinoma (TCC), is a type of cancer that begins in transitional tissue, which is found in the urinary system, including the kidneys, bladder, and ureters, as well as certain parts of the prostate.
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.
Overview Papillary urothelial carcinoma is a type of bladder cancer. It starts in urothelial cells in the bladder lining.

Inverted urothelial papillomas may have focal polypoid exophytic areas, yet lack true papillae (Figs. 4.13, 4.14) (efig 4.19).Within these broader projections are solid nests and cords of urothelium, cytologically characteristic of inverted urothelial papilloma, differing from a central fibrovascular core lined by urothelium seen in urothelial carcinoma and exophytic urothelial papilloma.

Renal parenchyma often develops a high-grade scirrhous mass formation and turns to a malignant tumor. In urothelial carcinoma, the organ which can get affected with malignant attacks is renal pelvis, ureters, and bladder.
