Background Precise identification of histologic variants in urothelial carcinoma (UC) is
important because some histologic types have a poor prognosis and clinical management …

OBJECTIVE To evaluate and compare the cytopathological expression of the five major
histological types of carcinoma in situ (CIS) in urinary bladder washings from patients with …

Urothelial carcinoma represents a diverse group of tumours with distinct histologic subtypes,
each exhibiting unique cytomorphologic features, architectural growth patterns, and/or well …

Introduction The ability to consistently diagnose low-grade urothelial carcinoma (LGUC) in
urinary tract cytology (UTCy) specimens remains controversial, as the reported sensitivity of …

BACKGROUND Urinary tract (UT) cytology has been used successfully to diagnose high‐
grade urothelial carcinoma but is reported to have poor sensitivity for low‐grade urothelial …

Background and objective Urothelial carcinoma (UC) demonstrating variant histologic
differentiation is associated with poor outcomes, and certain variants exhibit differing …

Introduction Compared to urothelial carcinomas (UCs), the cytomorphology of renal cell
carcinomas (RCCs) is underdescribed. This study aims to investigate whether UCs and …

Urine cytology is routinely used for early diagnosis and monitoring of patients with hematuria
or a history of urothelial carcinoma, but its clinical utility is greatly diminished by a high …

Bladder cancer can be classified histologically as urothelial or non-urothelial. Urothelial
cancer has a propensity for divergent differentiation, which has increasingly been …

Introduction Urothelial carcinoma (UC) requires lifelong monitoring, commonly through
urinary cytology and cystoscopy. Urine cytology has a relatively high sensitivity for detecting …
