Epidemiology
  • 80% male; age range 61-76 years
Micro Description

  • Often prominent lymphoid infiltrate (usually T cells)
Positive Stains
Negative Stains
  • Epithelial cells: lymphoid markers
Differential Diagnosis
  • Lymphoepithelioma-like carcinoma: tumor cells appear in syncytium, not as single cells
  • Lymphoma: no urothelial carcinoma component; positive for lymphoid markers and negative for keratin
  • Plasmacytoma: associated with myeloma, plasmacytoid cells with abundant cytoplasm and eccentric nuclei, often binucleated forms, no classic urothelial carcinoma, CD38+, CD138+, negative for keratin
