Handling2 Partial cystectomy Radical cystectomy - female, female adnexae and ant vagina - male, prostate and seminal vesicles Anterior exenteration - +AP resection

Name and Classificiation

Flat Lesions Inflammatory Dysplastic CIS ? denuded

Is it CIS?

Does Immuno help? Cytokeratin 20 CD44/cyt5 MIB1 p53

Is it papillary? Inflammatory Metaplastic Neoplastic

Is it Invasive? Scarring Involvement of Von Brunn’s nests Inverted growth pattern

What is the stage? Diathermy artefact – stage pTx Muscularis mucosae Vs Muscularis propria Fat invasion Muscularis propria invasion Invasion into the prostate

Urothelial Ca/TCC Grading Differentiation A few interesting subtypes, micropapillary, nested Immunohistochemistry, cyt 7, cyt 20, Gata3, 34BE12
