Histologic Definition of Papillary Urothelial Neoplasm of Low Malignant Potential PUNLMP is defined as a papillary urothelial tumor that resembles urothelial papilloma with delicate papillae, but has increased cellular thickness of normal-appearing urothelium, usually more than seven cells thick. For example, papillary urothelial neoplasms of limited malignant potential (PUNLMP) as well as low-grade papillary carcinomas reveal CK20 limited to the umbrella cells and CK5/6 staining confined to the basal layer, identical to the distribution of these keratins in the normal urothelium (Figure 2). Besides urothelial papilloma (UP) and papillary urothelial neoplasm of low malignant potential (PUNLMP), as described in the former classification, the new classification also includes new entities such as urothelial proliferation of uncertain malignant potential (UPUMP) and urothelial dysplasia (UD). Importantly, the current classification system provides detailed histological criteria for papillary urothelial lesions and allows for designation of a lesion (papillary urothelial neoplasm of low malignant potential) with a negligible risk of progression.

Low-grade papillary urothelial carcinoma: These tumors tend to grow slowly, but they can come back after treatment. On 11/23/09 the patient had urine cytology diagnosis “positive for malignancy, favor low grade papillary urothelial carcinoma.” On 12/28/09, the bladder biopsy showed “urothelial neoplasm of low malignant potential.” SINQ 20081086 only addresses the example of a positive FNA/biopsy followed by a negative resection. Low-grade papillary urothelial carcinoma, abbreviated LGPUC, is a very common indolent form of cancer that arises from the urothelium. Urothelial bladder neoplasms are extremely rare in the first decades of life, with an incidence of 0.1–0.4% and less than 35 cases described in children below ten years of age [1,2,3].The most typical form of young age is the Papillary Urothelial Neoplasm of Low Malignant Potential (PUNLMP), which is biologically indolent and low tumour grading and staging.

For this purpose, 34 primary in-house cases diagnosed and treated between 1998 and 2008 were identified from our medical records. For practical purposes patients with PUNLMP should be treated similarly to patients with low grade, noninvasive urothelial carcinoma. Papillae are slender with minimal branching.
