Stromal and Epithelial Architectural Alterations Mimicking Invasion (Pseudoinvasion) in Noninvasive Papillary Urothelial Carcinoma
CONCLUSIONS.—: Given the correlation with size and presence of infarcted papillae, we suggest the possibility of tumor ischemia/infarction as a plausible etiology of pseudoinvasion. Awareness of this phenomenon is important for the accurate diagnosis of invasion in papillary urothelial carcinoma.PMID:38133938 | DOI:10.5858/arpa.2023-0185-OA
