Chromatin Phenotype Karyometry Can Predict Recurrence in Papillary Urothelial Neoplasms of Low Malignant Potential
BACKGROUND A preceding exploratory study (J. Clin. Pathol. 57(2004), 1201-1207) had shown that a karyometric assessment of nuclei from papillary urothelial neoplasms of low malignant potential (PUNLMP) revealed subtle differences in phenotype which correlated with recurrence of disease. AIM OF THE STUDY To validate the results from the exploratory study on a larger sample size. MATERIALS 93...
متن کاملBladder papillary urothelial neoplasm of low malignant potential in Chinese: a clinical and pathological analysis.
Papillary urothelial neoplasm of low malignant potential (PUNLMP) had the incidence of low and definitive recurrence. Therefore, few studies showed that the relationship between pathological factors and the prognosis of patients with PUNLMP. The aim of this study assessed the linkage of pathological factors and prognosis of patients with PUNLMP including the presence or absence of mitoses and t...
متن کاملPapillary Urothelial Neoplasm of Low Malignant Potential in a 9-year-old Boy: A Case Report
Papillary urothelial neoplasm of low malignant potential (PUNLMP) is rarely diagnosed in paediatric patients under the age of 10 years. We report a case of bladder PUNLMP in a 9-year-old boy. The kid presented with painless gross haematuria. Ultrasound and computed tomography imaged a papillary mass in the bladder. Sixteen months follow-up detected no evidence of recurrence after resection of t...
متن کاملImmunohistochemical Differentiation between Urothelial Papillomas and Papillary Neoplasms of Low Malignant Potential of the Urinary Bladder.
BACKGROUND Urothelial papilloma and non-invasive papillary carcinoma are common neoplasms of the urinary bladder. Distinguishing papillomas and papillary carcinomas, especially the low grade type, is often debatable on the basis of histological features alone. MATERIALS AND METHODS We investigated immunohistochemical expression of cytokeratin 20 (CK20), p53, and Ki-67 in a group of 20 urothel...
متن کاملPapillary Urothelial Neoplasm of Low Malignant Potential (PUNLMP) After Initial TUR-BT: Comparative Analyses with Noninvasive Low-Grade Papillary Urothelial Carcinoma (LGPUC)
Purpose: To verify if the distinction between papillary urothelial neoplasm of low malignant potential (PUNLMP) and noninvasive low-grade papillary urothelial carcinoma (LGPUC) reflects a different biologic activity. Materials and Methods: We reviewed and analyzed the clinical data from 678 patients who had a diagnosis of PUNLMP (n=53) or noninvasive LGPUC (n=625) after initial TUR-BT for bladd...
