B, Enlarged pleomorphic nuclei with preserved chromatin and irregular, wrinkled nuclear membrane (“raisinoid” nuclei) diagnostic of chromophobe RCC. C, Tubulocystic carcinoma composed of tightly packed tubules and cysts. Prominent nucleoli are noted. D, Eosinophilic clear cell RCC with rich sinusoidal-like vasculature.
