Lung SCC negative 1.2.2. Patients with papillary urothelial neoplasms of LMP have increased risks of local recurrence, progression, and death from bladder carcinoma. Long term clinical follow-up may be indicated for patient management. Papillary urothelial neoplasms of low malignant potential are characterized by an orderly proliferation of urothelial cells without significant cy tologic atypia. Previously, numerous diverse grading schemes for bladder tumor, including the 1973 World Health Organization (WHO) classification, existed whereby one of the major limitations was poor inter-observer reproducibility among pathologists.

Miyamoto H, Miller JS, Fajardo DA, Lee TK, Netto GJ, Epstein JI. Normal thickness is 4-6 cells; Atypia absent to minimal Most studies demonstrate prognostic differences between PUNLMP and papillary low-grade urothelial carcinoma, with recurrence in 25% to 47% of the former and 48% to 77% of the latter. National Library of Medicine 2 David G. Bostwick, M.D. The histologic appearance is similar to papilloma except for urothelial thickening. Low malignant potential terminology may not reflect the true biological behavior of these tumors. PUNLMP is pronounced pun-lump. Papillary urothelial neoplasm of low malignant potential (PUN-LMP) was introduced as a noninvasive, noncancerous lesion and a separate grade category in 1998. The papillae are well formed and lined by urothelial cells that are usually more than seven cell layers in thickness. Knowledge of the long term outcomes of patients with papillary urothelial neoplasms of low malignant potential (LMP) is limited. Additionally, no study has addressed the outcome of PUNLMP exhibiting inverted growth. However, urine cytology is negative in most cases. Patients and methods: Of 475 consecutive patients with newly diagnosed bladder tumours between 1976 and 1993, 330 (69%) had superficial (Ta and T1) tumours and 53 (11%) were diagnosed as having PUNLMP. 1999 Nov 15;86(10):1890-2. doi: 10.1002/(sici)1097-0142(19991115)86:10<1890::aid-cncr2>3.0.co;2-j.
