Group 2: EC with clear cells. (a) Endometrioid adenocarcinoma with mucinous features. Intracytoplasmic and extracellular mucin are prominent in this field. The neoplastic cells have cytoplasmic clearing and well-defined cell borders at the center of the image. Low-grade nuclear features are noticeable throughout the lesion (100x); (b) the glandular and solid patterns of an endometrial yolk sac tumor. The neoplastic cells have significant nuclear atypia and cytoplasmic clearing (100x).
