Microscopic examination

In uncertain cases, perform immunohistochemistry for S100P and GATA3, where positivity indicates urothelial carcinomas with squamous differentiation (positive in 83% and 35% respectively), and negativity indicates squamous cell carcinomas (positive in 9% and near-0%, respectively).[1]
