Noninvasive low-grade papillary urothelial carcinoma with degenerative nuclear atypia: a grading pitfall.

Human pathology - 1 Jul 2021

Matoso Andres, Parimi Vamsi, Epstein Jonathan I

Abstract excerpt

Noninvasive low-grade papillary urothelial carcinoma is a papillary neoplasm with orderly appearance and mild nuclear pleomorphism. Some cases show significant nuclear pleomorphism with degenerative atypia leading to grading difficulties. A retrospective review of the pathology files identified 16 cases diagnosed as noninvasive low-grade papillary urothelial carcinoma with degenerative atypia. Fifteen cases were...
