Histologic features of silent subtype 3 adenomas. The tumors showed diffuse solid growth (a and b) and consisted of spindle-shaped (b) and epithelioid (b) cells with chromophobic to variably eosinophilic cytoplasm (a and b). The tumor cell nuclei (b) show prominent structures that correspond to spheridia (curved arrows); occasional intranuclear pseudoinclusions (arrows) were also readily identified.
