DOI: 10.1016/j.humpath.2021.04.002
Abstract: 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. Retrospective review of the pathology files… read more here.

DOI: 10.1016/j.urology.2018.10.023
Abstract: OBJECTIVE To determine tumor recurrence rate of low-grade, papillary, and non-muscle-invasive (TaLG) bladder tumors in patients who have asymptomatic bacteriuria (ABU). Microbes in the urine trigger immune responses like intravesical Bacillus Calmette-Guerin, suggesting that common… read more here.
